Great
I coach high school football. Use this to time operation time for my kickers and punters, plus hang time. Had my previous watch for ten years.

Very responsive & sturdy buttons
Owned for 1 month, works quite well for motorcycle instruction classes for measuring timed braking/acceleration distances. Hope longevity will not be an issue. Happy with purchase.

it fits well into a large hand and is easy to read
Buttons start a little stiff, but it breaks in quickly and works well. The device is larger than I remembered, it fits well into a large hand and is easy to read.

Handy item for runners or walkers
Good value for the price. The larger size is easy to handle and read.

NOT 1/1000th second precision
The Robic SC-505W stopwatch is advertised as being 1/1000th second precision to 24 hours. I purchased two of these units as timers for a test pinewood derby track, which requires high accuracy over about a 2 second range. I carefully opened the units up and connected an external electronic trigger circuit to their start/stop and reset buttons. To test the two units, I used the electronic trigger circuit to trigger their start/stop buttons at the exact same time. I also connected a digital oscilloscope to the trigger circuits and start/stop buttons to confirm the integrity of the test. What I found was that there was up to a +-40/1000 of a second difference between the two test units over a 2 second period of time! The test was repeated 20 times; in 6 cases the times were identical, in 5 cases sample A had a greater time, and in 9 cases sample B had a greater time. In otherwords, the error was not repeatable, therefore, I could not simply offset the error and still use the SC-505W units as timers. I later called the distributor for Robic and explained what I had found. The representative stated that the units were accurate to something like 2 seconds over a 1 year period of time. I explained that I was not looking for accuracy over 1 year, rather accuracy over a time period less than 10 seconds. His final statement was "what do you expect from a $30 stopwatch". In fairness to Robic, I tested another inexpensive timer and found similiar results, but that timer at least only advertised 1/100th second precision. I should also point out that the internal and external construction of the SC-505W was very rugged. But, it is simply not accurate, even at 1/100th second precision, never mind 1/1000th precision.

It works very well
I use it swimming meets and it has worked flawless. It is cost effective and works very well.

just right
This stopwatch is easy to use, but also very accurate. I was so tired of multi-function clock/stopwatches because for some reason it's always in 'clock' mode. This has enough features, like lap counting, to make me excited, but few enough features that I could figure it out in only a minute. This is the back-up back-up timer for our cross country meets.
