## Customer Reviews

### ⭐⭐⭐⭐⭐ Loud and Fantastic Battery Life
*by M***E on November 10, 2021*

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.

### ⭐ Not for running....
*by H***C on October 20, 2023*

"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.

### ⭐⭐⭐⭐⭐ Great product / works as intended.
*by J***N on August 8, 2023*

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