Accusplit A601X Pro Survivor Stopwatches with Special Million Cycle Switches

As a stopwatch, which is my only daily use. it is just great. It replaces one I've had for some years. The R button on it, which I constantly use, began to not always function. Had to push it two or three times for it to take. Gave it a 4 star rating because the instructions how to set the clock did not work as written. I do not use it as a clock but sometimes, when exercising, I like to see what time it is.

My experience when used that the start and stop button response a little stiff and sticks sometimes. This is a problem because I measure efforts within tenths and hundreds of a second. Need to spend more money for a good timer.
