I am a 50 something trail hiker/runner. I have to use reading glasses for my phone, watch, etc. I HATE having to wear my glasses when I exercise. This is THE perfect interval timer. I can see the time without glasses AND it has optional mode for time. I was worried about the size. But, I wear child size gloves as an adult and this fits perfectly in my hand. I can't recommend this enough. If you are on the fence about this product I highly recommend it. It works great! I purchased in yellow and attach it with a clip to my hiking/trail/water pack.
