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

The green numbers are barely visible outdoors, even with many attempts at various shade protection. Most swim/deck clocks are much more visible with red numbers. Also the numbers are way too small. Two inches tall should be a minimum.
The highly reflective face plate is a significant design flaw. It acts like a mirror and reflects the swimmer and pool background and makes the clock numbers invisible outdoors.
The clock stays dry on deck but I would be hesitant to put it in the water after reading other reviews. Because of the reflectivity problem I am thinking that putting the clock in a zip loc bag would keep the clock dry and make it more readable than the "waterproof case" it comes with. I have no confidence that I have sealed the gasket and it was a very difficult effort just to make an attempt.
The only reason I gave it 2 stars instead of one star is because the concept of a personal swim clock is a good idea. It's too bad that this clock is such a disappointment as my swim team would have bought several if they were actually useable on a pool deck.
