So I got my second flex last week, after the first one was broken out of the box. I can't say enough how easy it is to return defective products to Amazon, very user friendly. Now for the flex. I'm totally sold on fitbit, yes I have a few. . I started out with the Surge. The surge is a great product in its own right, but is too bulky for me to wear every day in the hot summer. If you need all the bells and whistles the surge is the way to go. The surge also costs 250.I needed heart rate monitor sometimes because my health sucks. I'm 46 and I've had 2 mild heart attacks and now have chronic idiopathic pancreatitus. I spend a lot of time in bed, but I still need to do some easy physical activity, which for me is walking. Since the surge was too sweaty and bulky for me in the summer months, I tried the Charge HR next. I really like that one too, but it cost 149..but it's alot less bulky and has a great accurate enough heart rate. But it still got sweaty under the wrist and I was worried about it getting harmed when I do my housework. So then I got the flex.. The flex is very slim and can be loosely worn because it doesn't track heart rate.. Which for me is fine for most days when I don't need all the features. So no sweaty wrist, and, you can purchase many different types of replacement bands to match your outfit. The flex does track, steps, calories, miles and sleep which must be turned on manually. The flex also only costs about 80 bucks so I'm not as concerned about it getting wrecked doing heavy duty spring cleaning. The cost also makes it easy to get introduced to fitbit. The software and app are amazing and very social and user friendly. The app also allows you to hook up different trackers and set your goals up for what you want to do. Having friends on the app allows you to compete and stay motivated too. The flex uses 5 LED lights to help you see how you are doing through the day. Each light represents 20% of your goal. For me, I find the lights more motivating than having the raw data on my wrist because you have to work harder to get all the lights and complete the goal for the day. And, unlike the surge and charge that need to be charged every 3 days, the flex only needs to be charged once a week which is a lot easier if you like me have a crazy busy life.. So get a flex, you will love it and the fitbit community.

I've been using my Fitbit (and the website program) for over two weeks now. It's not a ton of time, but I have to say that I am absolutely in love! While I had a bit of difficulty figuring out the ins and outs of the product (there's no user-manual in the package; you have to go to the website and click through the product to learn about how to go to Sleep Mode, how to charge, how to install, etc), once I did figure it all out it's been a breeze and surprisingly motivating. Just the fact that it's on my wrist reminds me (and encourages me) to get moving; I find I WANT to hit my 10,000 step goal, I'm DRIVEN to get there no matter how tired I might be, not to mention that the website is fantastic for tracking your calorie-intake and -outtake to really get a concrete understanding of your success in your weight-loss regiment. I love that the website charts my daily stats, from steps and distance to weight and progress towards my goal, and I have been religiously tracking myself, feeling great pride when I'm told I've reached my goal :D The Fitbit Flex also has a sleep mode. Before I bought it, a friend of mine told me it would wake me up before my next REM state so that I wouldn't wake up groggy. Fibit does not say this simply because it's not true; it was a misrepresentation by my friend. BUT! The Fitbit does track how long it takes to fall asleep and how many times you 'wake up' (or move about) during the night, and it gives you a 'sleep efficiency' percentage that is actually really helpful. I've been enjoying this feature more than I expected because it's showing me that my sleep efficiency is TERRIBLE!!! 55% on a good day! AH! But it makes sense to me because I'm always tired and usually need to be in bed for 10+ hours to feel rested... no wonder, considering an 8-hour sleep only gets me around 4 hours of ACTUAL sleep! So, now that I know this (thanks Fitbit! ^.^), I've been taking steps to try to get better sleep: no computer before bed, watching what I eat (no chocolate or caffeinated tea), etc. It's still early, but I'll continue to use Fitbit to see if it's working and compare to my past nights' sleeps :) A final thing I want to talk about it the Customer Service at Fitbit. In a word, it's WONDERFUL! For my experience, I bought the tangerine coloured Fitbit (I LOVE colour!) and simply adored the brightness of it! Until a week in when the orange started to turn black.... It's not a fault of the Fitbit, I know it was/is something of mine that the Fitbit is rubbing against when I wear it that is rubbing off onto the Fitbit and staining it (though for the life of me I can't figure out what! My coat? Sweater? Sweat pants? Jeans? Furniture???? What is it!!?!?). The pretty orange wristband is now completely black on the edges... it's OK for casual wear, but if I want to wear something nice and keep my Fitbit on, it just looks shabby, and it made me really sad :( So, I contacted Fitbit Customer Service. I sent an email with a picture showing the discolouration and explaining that my tracker was in perfect shape but that the discolouration of the orange wristband made me not even want to wear it anymore because it just looks aweful. Within two days, I received a message from Fitbit Customer Service saying they would be happy to replace my orange wristband with a black one instead (no discolouring! YAY!!!!). I have to say, I am THRILLED with their response! Not only with the speed and efficiency of it, but with the fact that they were so understanding, friendly, and respectful of me. The only questions they asked were my name and address so they could send the replacement, no suspicion or berating questions, and as a customer I super appreciate that :) There seem to be less and less companies with great Customer Service, but Fitbit is definitely one that has fantastic Customer Service :) I feel confident and comfortable buying from them and recommending the products now that I know that they truly put their customers first. Anyway, that's my experience with Fitbit. I absolutely recommend this product, specifically this company rather than another version of the same product (I know there are lots out there... Fitbit just outshines them imo). Hope this review is helpful! :)

SUMMARY: This device will not do anything for you, but it will help you make good decisions about what you need to do yourself. Fitness is hard work. If I had to sum up what this device is doing for me, it is this. It is keeping me utterly honest about everything. I cannot lie to myself about how many calories I'm burning. It won't let me. Just knowing there is a record motivates me to make sure it is a good one. It's the same effect one gets if they know they are being graded. ****** THE LONG VERSION I have been using the fitbit flex for five days now and I have fewer pounds and great fitting pants already, so it would be hard to regret my purchase. I went ahead and set my fitbit up to integrate with MyFitnessPal as soon as I set it up, so I have no idea how it works without it. Setting it up was a breeze. Go here: http://www.myfitnesspal.com/apps/show/fitbit and follow the instructions. Once it is set up it gives you a warning that you should only enter your food on MFP to avoid double entries. I have entered everything I eat on MFP, and the info magically finds it's way to my fitbit dashboard, and there have been no problems whatsoever. Entering exercise is a little more complicated. Once you've done the integration, your MFP exercise entries will require one extra step--the start time of your exercise. My entries consist mostly of running and swimming. Technically, I don't need to enter the runs, since the pedometer takes care of them just fine, but when I do enter a run, the two apps manage it well. MFP gives the start time and duration of the run to fitbit, and fitbit takes that info and does some calculations that take the pedometer data into account, and comes up with a number of calories burned. I have run into one snag...if I edit the start time of my entry in MFP after I've already logged it, it causes the exercise to log twice on fitbit and I have to go into fitbit and manually remove the double entry. Sometimes I'm lazy and I don't enter the runs in MFP and I just let fitbit use the pedometer data exclusively....I've not taken a close enough look at the difference to comment on it, but it seems to work well either way as far as calorie counting. I just prefer knowing the speed and duration of specific intervals and that data is lost if I don't enter it into MFP. I take the flex off when I swim laps, since I have a watch that counts my laps and distances for me and wearing both would be cumbersome. I enter my swims manually into MFP, and fitbit automatically calculates it all. I've had no problems. You'll have a new thing in your MFP display too. Your exercise log will have a "fitbit calorie adjustment" entry. For whatever reason, fitbit lets me eat just a little less than fitness pal does, so the math is obviously a little different on the two programs. If you are tall and have abnormally long legs like me, you may have to adjust fitbit's default stride settings. Their website can tell you how. The biggest lifestyle change for me has been brought about by the in-your-face awareness of just how sedentary sitting at a computer is. On days when I work at my desk, 6PM rolls around and I've only got maybe 500 steps logged. I'll hit the gym to do my 3 mile jog, and still be no where near the 10 thousand step goal that is the default setting for the fitbit, so I end up walking on the treadmill until I get there. I find myself going on long walks after my swim too. Maybe I'm crazy, but I can't stand to go to bed without meeting my step goals first, even if I've logged a long swim, but whatever the reasons, it is working, and fast. I am losing weight again after stalling out for quite a while. I mentioned only having 500 steps after a day at my desk. Yesterday I had my first day away from my desk...shopping, a little yardwork, housework, just getting all the little things that need done around the house...at 5pm I had logged 8000 steps and was almost to my goal. I mention this because I think this is what makes the fitbit worthwhile. It quantifies how sedentary your life is on a given day and then tells you exactly what you need to do to make up for it. And I know, if you are a desk worker like me, that 10,000 steps is going to seem a bit ridiculous after a day at the office, but trust me, if you can make yourself make up for it, you will be blown away by the results. I hesitate to put the numbers down for my weight loss over the last 5 days, because I have frankly lost weight faster than I should and I don't want to invite trolls or create unrealistic expectations...everyone is different. I am eating more than 2000 calories a day (within the recommendations of the app set at medium plan intensity), I'm not starving myself, and yes, my legs were pretty tired the first few days, but I promise, I feel great. I'll be at my goal of 145 in a couple of weeks at this rate. The fitbit didn't lose that weight for me...I worked my butt off all by myself, but fitbit helped me figure out what I needed to be doing. **** I know this review is getting long, but I wanted to mention a couple of other things. I LOVE the sleep monitoring. I have random bouts of insomnia, and I sometimes wake up repeatedly all night, and this thing has done a brilliant job of measuring how much time I've actually spent sleeping vs. how much time I've been in bed. And that number of hours of actual sleep correlates almost perfectly to how I feel, mentally, through the day. The default sensitivity is perfect for me...though I have seen it isn't so much for other people. It is easy to turn it on for naps too. Just tap it five times when you lay down, and again when you get up. You can fix it manually in the website if you forget...it will still have the movement data regardless of whether you tap it or not, it just needs to know when you were sleeping to fix it all. It accidentally goes into sleep mode here and there...once when I was using a hammer drill, once when I was using a hammer, and once when I was shaking a bottle of cat antibiotics to mix it, but when that happens, you know because it vibrates, and if you tap it five times right away to bring it out of sleep mode, it won't mess up your data.
