Just wanted to share this counter modification i did. I always had a problem with these rubber buttons always counting more than one counts and giving wrong reading. Just changed mine to a tactile push button which fits in nicely and gives the correct counts. You will need some general soldering skills and a pcb drill machine.
If you want to try this, just make sure you take care of the display as it is very weak and breaks off easily.
Also have you guys done some similar projects? #religion
