I bought this stopwatch to replace a Radio Shack stopwatch I've had for 20 years - thought the batter had died, but when I took it apart to look for the battery it started working again (water seal shot in the process of taking it apart though).Bought this stopwatch as a replacement. It's about a quarter the heft of the Radio Shack (both made in China) - it's light as a feather. It keeps very accurate time (in clock mode) and the stopwatch functions pretty well, though I find the button mechanism a bit flimsy. It does not employ a backlit function, which I occasionally found very useful. It wasn't clear on the stopwatch or instructions what kind of battery it takes (some of these, identical-looking) take two batteries - so I took it apart. It does indeed take a single CR2032 battery. It's easy over years of time to loose track of the battery required, so I feel the mfg is remiss in not stamping the battery model on the back of the case. I like the more solid (and rubberized) feel of the heavier Radio Shack stopwatch, but the bottom line is (with minimal use so far) it seems to do the job well, as long as you don't require a backlit display button. Finally you NEED the instructions to hit the proper combinations of buttons (not intuitive) to set the time or specify 12-hour or 24-hour time, etc. So apart from these issues, it does what it's supposed to at what I consider a bargain for a stopwatch.
