I use the stopwatch for timing....it works perfectly! Would highly recommend....

The lap counter is great.  The button you push is easy to use, which is much better than one I got a long time ago.  Notice how the picture shows it on the person's hand.  I wear it like that BUT I turn it upside down, so that the button is naturally closest to the thumb.  It makes reading it a bit tricky, but much easier to use.  For me, I know roughly how many laps I've done, so I only have to read it while swimming once or twice.  I've gotten use to reading it upside down.
Having it keep track of laps, time and avg time is great.  It took a little while getting used to pushing the button at every wall, but it soon becomes a natural habit.

I originally bought the red model that calculates everything in one device. But when you are swimming you need SIMPLE, not complicated. So I purchased both the lap counter and the timer separately. I put them on both of my index fingers and they work great!  It is so much easier than trying to watch a swim clock and is easy to see in the water.  You use your thumb to push button so there is no interruption while you are swimming.  Highly recommended!!!!!

Pretty nifty little device. I swim at LA Fitness which doesn't have a pace clock and this little stop watch helps me stay true to my intervals. I do find it uncomfortable to keep it on my finger for long sets. Therefore, I generally keep it on the edge of the pool and only put it on my finger for the last couple of sprints in each set. Also, easy to use and durable.
