Review on Bone Bike Tie Connect: Universal Mount for Garmin GPS Cycling Computer & Phone - Handlebar & Stem Compatibility by Jason Maciel

Bought a running tie set because I was looking for a way to hold my phone on my arm while running and also be able to easily access my cell phone to take pictures when I'm not at home. It ticks all of those boxes, but oh my, it bounces a lot. I have a galaxy s9+ and a fairly small (10.5 inch biceps). If I tighten the strap so tight that the phone barely bounces, it's like a tourniquet on my arm and my biceps start to cramp. Tried this morning with phone upright, tomorrow I'll try with phone horizontal. Other than that, it didn't slide much and was easy to use, but having to tie it tight enough not to bounce is a deal breaker.
