Review on ๐Ÿƒ GO2 Endurance Workout Device: Enhance Breathing & Oxygen Flow During Running, Cycling, and High-Altitude Activities - Made in USA by Troy Jennings

Revainrating 5 out of 5

Faster, keep running!

I've been using my go2 for quite some time now and I've noticed an improvement in my endurance! I could ride a little longer before I get really tired and I can't wait to train more with him and set the best marathon finish time I can! Before I could walk comfortably with it, to my surprise I didn't feel any limitations the first time I used it! ๐Ÿ‘๐Ÿฝ

Pros
  • Decent performance
Cons
  • There are shortcomings
