Review: Good price for a quality product - Bought these for an outdoor storage box. They seem high quality and so far they have not corroded.
Review: Excellent and durable - Don’t waste your money on no name crappy locks or you’re just going to have problems that waste more time and money than you can save on cheap crappy locks. These are very solid. Only thing to watch out for is don’t lose the little key-like tools used to set the combination. These aren’t keys, just little twist levers only needed to change the combo (which requires unlocking the lock so they don’t need to be keys).

## Questions & Answers

**Q: Does this lock have any harmful chemicals Prop 65**
A: Don’t put it in your drink or cook with it, if it mixes into your drink or food it could make you sick but I believe the report said you’d have to do that 834 times to have a negative affect on you. 
But on a side note I read just the paper from the Prop 65 rule could make you violently sick if you eat all the paper in just one setting.

**Q: Is it for outdoor use?**
A: It hasn't fared well for us. We have an older one which held up for about 3 years before needing to be replaced. The lifetime warranty allows you only one replacement, so it really isn't a lifetime warranty at all. If you live near the beach, consider yourself lucky if it works for 2-3 years. That said, it is for outdoor use, just expect to lubricate frequently especially after rain or if you live near saltwater.

**Q: What's the diameter of the shackle? I need to make sure it can fit through a hole in a security box.**
A: 5/16"http://www.allpadlocks.com/cgi-bin/ez-catalog/product_images.cgi?account=X380790;product_id=M178;image=images%2Fcatalog%2F178sketch.jpg

**Q: Lost the change key -- how to reset the combo without it?**
A: you can just use a small screwdriver to push in and change the combo while doing so. The Key really just holds down the bar inside for you.

### ⭐⭐⭐⭐⭐ Great for sheds.
*by R***Y on March 7, 2016*

This is a review of the Master Lock 178D Set Your Own Combo Padlock. I will do my normal list of specs-cool features and then list a summary as to my thoughts after using. -This is made of die cast metal and has a black finish to help protect it from the outside elements.) -It has a 2” wide die cast case and a 1” shackle. Diameter of the shackle is 5/16”. -Comes with 1 change key. -Operate by using a four digit number combination you set. -Unlike a lot of locks, this is a very well built solid lock designed for outdoor use. -To use, enter the combo and push down the shackle and then pull it up to unlock. Summary – I am using these on my two sheds. The combo is easy to set. You simply unlock the lock – open the shackle, insert the key – turn 90 degrees, set the combo of your choice and then remove the key. I really like this feature as I wanted my two sheds to have the same combo so I do not forget and for simplicity. The movement of the dials has a slight clicking and bump feel as you move the numbers vs. being an easy roll. (Might get smoother with time.) I like this as it is easy to lock your digits in and know they are aligned right. Whatever you do, do not forget the combo. The key is only for changing the code and will not open the lock. I am very happy with this lock and all master locks in general so far. Good make and reliable. Highly recommend.
