Review on Gymboss Plus: Your ⏱️ Ultimate Interval Timer and Stopwatch Solution by Bam Reeder

Slightly larger than a matchbox and very light I find this to be the perfect tool for interval walking/running. You MUST download a copy of the instructions from the internet as I doubt even a NASA pilot could read them without using the Hubble telescope. Don't worry - just type "Gymboss Instructions" into your favorite search engine and they'll appear instantly. Although I'm hard of hearing, I only use it in beep mode because the frequency is comfortable for the elderly and easy to hear with the device on a belt. Vibrating stones and I could use them when the Gymboss is in one of my bags. Because it's small (and perfect), the clip doesn't extend past the device, so you can't fully attach it to a 1 1/2 inch wide belt. However, it stays in order and attaches securely to athletic pants with no issues. .After using it a few times, the three-mode setting makes sense and you can use it from memory.For intervals, the device is very versatile, giving you many options for time and interval frequency.Don't like AAA battery (not included, nor included) which I put in will last a long time but it says it has a low battery indicator so I'm not too worried.
