Review: Excellent quality. - Works great. Easy to use. Beeps are loud enough for me to hear when running with my AirPods in listening to music. I can see the screen clear as day when I look at it. Not sure why other people are having such a hard time seeing it but also not sure why you need to look at it. That’s what the beeps are for. If you are working out staring at the time on a little screen you aren’t working out.
Review: Umpires! Need a pitch clock? This is it. - Using this during high school varsity baseball umpiring for pitch clock enforcement. Set up with 12 sec and 8 sec alarms with 1 interval, no beep, loud vibrate. One button push to start, resets automatically after alarm, 1 button push to stop/reset before alarm. Better solution than Refsmart (dramatically smaller, easier to configure, no batteries to change, etc) at 25% the cost. While it was never designed for this use, I can see this easily and quickly taking over as the go-to pitch clock tool for many high school, JUCO, and lower level college umpires.

## Questions & Answers

**Q: Can this be set to a mode where the alarm is silent and it vibrates instead?**
A: Yes it can be set to vibrate only as the alarm.

**Q: Can a countdown be "easily and instantly” reset on the push of a button before reaching zero in case I want to start the interval over?**
A: Yes. You can press and hold the start button for three seconds and the timer will stop the countdown and reset itself back to the beginning. Please note do not apply hard pressure on the button, soft pressure will work just fine.

**Q: Can it be used an it be used  in a pool?**
A: It is supposed to be water proof. I had a friend who ran hers through the washer and it worked fine after. And I don't worry about it when I'm in the rain. But I have no experience with using it while it is actually being immersed in water. It is moderately loud, so assuming there wasn't a ton of other noise you might hear it from the side of the pool.

**Q: Are they all weather proof?**
A: The Charge model timer is our most weatherproof timer. It is made to be used outdoors.

### ⭐⭐⭐⭐⭐ Nice, minimalist design. Needs a couple of improvements.
*by N***R on November 5, 2025*

It's missing a few features I have on my interval app on my phone: 1) It would be nice to have different signals on the work vs. rest phases 2) It would be nice to get warning signals just before a phase starts or ends. And the vibrate only mode doesn't work for me. I often don't pick it up if I have this in my pocket. Might be more effective if you could make it press against the skin. The beep in loud mode is very audible, though, as long as you're not running next to busy traffic.
