Digital Counter

I read some reviews, and it is obvious, many people don't know how to use this product. They say the instructions are in Chinese only... that is mostly true. There is a "POWER" and a "RESET" button. That is English, and even the electrical contacts in the back are understandable. If they don't know what this device is, and don't look at youtu8e, that is NOT the fault of the product. I bought this to count switch closures of a reed switch, but not the switch/sensor that is included. My hope was that the battery would last, at least a week. It worked perfectly. It does NOT turn off, to save power... which is what I want. 7 days later, it is working great. [Side note, when you take out the battery... 30 seconds later, it was still running... so I can tell you, this runs on microamps and I expect the battery to last a long time.] The digits are very readable. Installed this outside of a window, protected from water. Seems to work so far, from freezing to 80F. My application has switch closures lasting 55mS to 60mS... and this 1/15th to 1/20th second closure is counted every time. 100% recommend to the DIYers that understand, this is just a counter that counts. As shipped, it counts when the included magnet comes into proximity to the included sensor. That's it. You need to know how to attach it to whatever your application is.

Finally had the chance to hook it up on my circular knitting machine. There are no understandable instructions - china - however, both wires go to power side shown in one of my pics. Everything used to make this moveable to other machines are also from Amazon in pic. I bought 8x2mm magnets bc the one that came with the counter was pretty big, these work great! Adhesive dots and a package of bendable closet hooks fit perfectly on the counter! Other than that - adhesive hook tape! Works fabulous!

Purchased this for my Dillon 550 reloading machine. It was easy to install, the batteries last a long time and the lcd screen is easy to view and clear to zero. I would definitely purchase another one if needed.

Do not order! This comes with zero English directions! How in the world does a person install something with critical row counting in a language we don't understand? Stupid!

This is a basic counter, and runs off AA battery located under the metal bracket intended for installation. So it is not "easy replacement". The life of the battery is not specified, but because the counter has LCD display, and the sensor is reed contact, it should be long enough. My counter sometime counted, sometime not. Troubleshooting shows that the sensor wire was broken inside isolation. I fixed it, but meantime discovered that it was a copper clad crap wire, it cannot be reliably tinned as on many other products from this geography. But it can be crimped into a connector for more reliable contact. In general, I am satisfied with price/performance, an English user manual leaflet will help.

Nice Counter for my Coil Winder.

I use this on my dillon 650 reloading press. Very accurate and easy to use. I highly recommend it for any repetitive motion machines

great buy

Have had 3 for my3 machines sadly 2 would not work so was refunded. Now I swap from 1 to the other brilliant little counter good seller’s refunded with no problem

It worked really well for the first couple of weeks, now it seems to be skipping rows and I have to mark my knited rows down. I bought this because the Sentro I bought had a crappy row counter that lasted about a day.

Per quello che serve a me fa un ottimo lavoro

Instructions in English would help as I don't read or speak any of the Chinese dialects

I use it for magnetic coil winding - it's so great, just hassle-free! Very glad I found and bought it.
