Review on Gymboss Plus: Your ⏱️ Ultimate Interval Timer and Stopwatch Solution by Adam Webbie

I've had 2 regular Gymboss for about 3 years now and the only reason I wanted a new one was because the screen on my other 2 went down to zero after a while, although there was still time and beeps/vibrates. I thought Gymboss+ would be perfect. Everything was fine the first few times. Now I only had it a month and a half and two important races that I needed were cancelled. I always set the number of intervals to 99 because I usually run 4 hours or more and so don't have to start again until after the countdown. The first marathon I used it for went well. No problem. I ran 50 km and just today another marathon. Every time he counted down from 99 he lost his settings and had to be reset to the correct interval time and number of intervals. I've reinstalled and changed the battery several times, it doesn't help. He goes in the trash because I can't rely on him. Very disappointed.
