I was wanting a running clock at the end of the pool since where I swim there is no pace clock. This clock does the trick. I turn it on and set it on the wall, and I can see it fine. I actually run two of them, and have one at each end for when I'm doing interval 25's or 75's or some odd number of laps. My biggest difficulty is remembering to pick up the one at the other end of the pool when I get out. I'm sure the other functions are useful, but having grown up in the 80's, I was trained on a running pace clock, so this does well for me. Just what I needed.

This is an awesome piece of equipment to fine tune your swimming. The pool I swim I. Has 4 digital clocks with four separate times. This clock has solved the multiple time issue for me. Oh … tremendous customer service I’m on my second one make sure your deals are tight.

2/2/26: I had really high hopes for this - a unique product serving a singular need for a very specific community, while supporting a swimming small business. But within a few months of use, it broke. Because it was still under warranty, the company was kind enough to replace it. But now it's out of warranty, no response to e-mail yet, and the replacement is broken with a few more months of use. I never submerged it. But the case leaks - every indoor pool is humid, I put it into the swim bag, and eventually, 1 drop of water will probably destroy it (that's my best guess as to why it won't turn on). When I e-mailed and informed them that the charging light was no longer working, I was told it's just a small bug... That's not a worthy product for $50, let alone $80 or $100. So I'm going to buy a $16 digital "waterproof" clock from Amazon, put it in a sandwich bag, and feel less bad about replacing it every few months. You have the opportunity to make a great product, and I hope that becomes reality one day.

I feel like a right jerk. The small business did right again and offered to replace it within 24 hrs, even after warranty. I read through all the reviews, and I don't find many others having this issue. I'm still going to try and place it in a Ziploc, to give it the absolute best shot. And if it lasts 6 months, I'll increase to 5 stars for sure.

6/26/26: said i'd update, and 5 stars for sure with the new version. they really listened to the feedback from other users - don't have to fish it in and out of the case (the old plastic one would build up moisture inside, which i think was part of the problem). can charge it without "taking it out of the case." case feels much sturdier. i still put it in a plastic bag, just in case...but no problems yet, and i've been using it weekly this time around bc no health issues for a bit. i tried an amazon stopwatch...first one, you couldn't see the numbers, the light would fade. second one, it wouldn't time right which is the absolute sole purpose of this; sure, i'd "swum faster" than ever before, but useless data. so to be back to a timer that times, is waterproof, designed for swimmers, visible, cost effective, with stellar customer service and response to feedback - i hope you get to buy this new version.

I had high expectations for this personal pace clock. As noted, it is not bright and can not be seen across a 25 yd pool. I purchased in April of '25, and it died in December '25. It had never been submerged or even in the water. I was very disappointed. However, Nate from customer service reached out to me even though the warranty had expired. We couldn't get the old clock working, so Swimnerds sent me a replacement. I did not expect such great customer service!

I use it in an Endless pool. Everything I was looking for. Very well thought out. Suctions easily to bottom of pool for easy reading while swimming. Highly recommend it
