I have used this watch several times now to time and count my laps at the pool. I like that fact that I don't have to count my laps now, and can let my mind focus on my technique rather than trying to remember what lap I'm on. The lap timer has pushed me to try and improve my times, which is a great incentive to work harder.
Pros are that it works in the water, it has many features for tracking your laps. The timer is nice for anything you'd like to measure in regular intervals. I use it for warm ups to make sure each stretch is half a minute. It stays on securely in the pool. The display is easy for my middle aged eyes to see.
Cons are that it would be nice if there was a pause feature, so I could take a break and not have it count as a lap. Also the tap screen is taking some getting used to. With a swim cap on, I can't always hear the beep. I have the tap screen set to the lightest tap to count since I won't be bumping it while swimming, but find that it still doesn't always register and I have to be very precise to tap it.
This results in double length times sometimes, or two second laps if I hit it twice thinking the first one didn't register, so the average lap feature is seldom right. I have been using the button on the side now, but they say not to use buttons underwater, so I hope using them wet doesn't wreck it.
I would also like to be able to delete workouts, but haven't figured that out yet. I don't think you can. And with all these features, it doesn't come with a manual. You have to download it, all 43 pages.
The cons aren't so bad, just something to be aware of. I'd still replace it with the same watch if I lost it because it does exactly what I bought it for.
