Gymboss Charge Interval Timer and Stopwatch

I have been using Jim boss timers for many years. They have made improvements overtime and I feel like this one is an improvement. I have used it every day for a month and still haven’t had to recharge it. I like the light and that model has, an option for the beep to be even louder. The rechargeable aspect of it is great. There is no other product out there that is as good as a gym boss.

I am doing the Jeff Galloway walk/run method and saw this timer mentioned on his website. The phone apps I had been using would lose gps and stop, or for some reason the audio would skip a round, and it was very frustrating. Got the and it works great!! Can hear it clearly, never skips, and vibration with sound helps for extra assurance I never miss it beep from my leggings pocket. The written instructions are useless, but the video guide is very easy to find on their website (Amazon won’t let me link it in this review) and once you watch it, it is very easy to set up. Very glad I bought it!

Muy bueno, ayuda a mantener el tiempo entre series y descanso, ayuda a la coordinación de los ejercicios

There's a bit of a learning curve for this device, but once you learn it, it's easy, portable, and the charge lasts forever. I use it for run/walk intervals and it's never failed me. Highly recommended for those who don't want to take along a phone or use up phone power with another app for intervals.

I was so excited to have a rechargeable timer, however this one is poor quality. After just 6 months the buttons keep popping off! I do not recommend- the regular battery operated timer is much better.

Haven't used yet but came with a broken clip but gets hidden when insert into slot.

Using it for running intervals. Got my fav color, and I like that it saves my watch battery, especially on long runs (did 14 miles with it in fog Saturday). Still learning the buttons, but I like it more and more. The notification, either ring or vibrate or both is good. I’ve tried it on my water bottle and on my shirt. Both work well.

I had used this twice and the third time the button fell off. The return was very easy and the seller made right immediately. It's a really cool stopwatch and I'm grateful everything was resolved quickly and in a great manner!
