Gymboss Charge Interval Timer and Stopwatch

This thing is great but I'm going to give you some advice. If you always wear it on your wrist, glue it onto the wristband. It's bigger than a watch and I tend to knock it on things and I had a brand new one and I knocked it off somewhere not knowing it and lost it. This is not like the model where you have to take the battery door off the back since with this one you just charge it from the side so if it's always going to be on your wrist glue it!!

Such an easy but handy tool when you're interval training. I wear earbuds when I'm working out, and clip this right to my sports bra. I can feel the vibrations and the beep and I don't have to turn my music down. The battery life is phenomenal, I've charged it once and have used it at least 3x a week for the past two months or so and it's still showing fully charged. I also love that this is rechargeable, I don't have to fiddle with batteries or the extra weight clipped to my clothing. Definitely spend the extra $4 to get this version, it's worth it.

I have purchased 3 in one year...when I first started buying the timer they would last at least a year or more. Now, 4 months. The buttons just stop working, leaving it worthless. Please make the button last more than 3 months, especially when you are asking almost $30 for a timer

I’ve had it on my gear for over a year, and while it hasn’t been in direct rain, it’s been exposed to extreme heat/cold. The screws are even rusted. It still works, but fortunately I don’t need to change the settings because the screen definitely is a dud lol. Ive only charged it a couple times, which is really impressive considering the abuse and temperature changes.

like the product, does what I needed to run intervals for running. Also, like I can charge the timer instead of having batteries.

I love that I can stick this in my pocket and just press the button on the top to start it. I don’t have to do anything to stop it. So convenient and worth the money!

The Gymboss Timer functions as designed. Audible and Vibration Modes are excellent - loud and detectable. I use it for time-based exercise routines (Tabata - 20 sec: work; 10 sec: rest). Allows for a wide range of settings. Battery is doing it's thing quite well. Have used the Timer frequently since it's receipt - charge level still indicates 2 of 3 Bars. Well pleased with purchase.

"Weatherproof allowing for use in heavy continuous rain as well as extreme sweat and humid conditions." - this is a lie. Bought 2 of these; one for me and one for wife. Both easily got moisture inside and never worked again. Actually, they worked until battery died because could not turn them off. Now that battery is dead, they won't charge and won't turn on.Mine was water damaged with no rain and just body sweat in Massachusettes running a half marathon. Wife's was damaged in really light rain in Rhode Island; also doing a half marathon.Terrible product. We have others that have lasted years in heavy rain and body sweat. The downside to those is they take batteries. I guess the technology of recharging capabilities makes them suceptible to moisture damage.
