My brain and my cardiopulmonary system are not very good at working together, and as a result I struggled frequently to keep my breathing in check and my HR low. Enter the Go2 device. I’m not sure about the VO2Max increase, because I don’t have a lab, but I do know after one week of training with this I ran a marathon PR and never struggled with my breathing rhythm, or felt short of breath. This is a fantastic little device for anyone who’s trying to improve their performance.

Excellent product, used this for 2 weeks now and run about 20 miles in 2 weeks...breathing and heart rate have gotten better to were I don’t feel tired after my runs. My first 3 runs I’ve had to pull the mouth piece out to spit a couple of times; but everything other than that it working.

The device works well for what it does, but after a while the effectiveness seems to lessen. I wish it came with an ability to put in new attachments to create more resistance, but I still use it and I get good training out of it. Not a bad purchase if you aren’t training super hard. I would definitely recommend it for beginners

It helps me with my breathing when I run and yes I did droll a bit at first, now when I feel I might possibly start to droll I take it out give it a shake and pop it back in. It certainly has taken off 6 mins off my 5K & 10K runs. I've used it when biking and don't take it out for fear of it dropping out of my had and not being able to find it. I did find the first couple to times I used it the sides of my mouth was a little sore, but not so much now. It's a game changer and I would say it's worth the money

The packaging doesn't come with much and outside of watching videos and reading the small paper that came with it I had no idea how to get started using the GO2. However, I learned this is one of those products that you have to use more and learn how it's supposed to work. I wouldn't recommend this to a newer runner, but someone who does cardio somewhat regularly. Cut a minute off of my mile time and still improving. I'm rating low due to the learning curve associate with initial use.

I wanted to like this thing but they just throw too many curveballs at you to use it properly. No instructions at all, no suggested usage, this thing is just take it out and you’re in your own. It would be halfway usable if you didn’t excessively drool the entire time you have this in. You can’t focus on training if you have to pull it out mid run or cycle to spit, or keep wiping your mouth during your session. It’s pretty annoying to use honestly. Wish I would’ve just paid the extra money for the airofit. This thing costs way too much to be so incomplete.

I have been using my go2 device for quite some time now and I’ve noticed an improvement in my endurance! I could go a little longer before actually getting tired and I can’t wait to train with it more and achieve the best marathon finish time that I’m capable of!👍🏽👍🏽👍🏽 PS: I expected some a couple of weeks before being comfortable running with it but to my surprise, I actually did not feel restricted in any way on my very first use!👍🏽

Have been using this with a variety of different workouts as I do triathlon training. Have used on indoor biking sessions, runs (short and long), and body weight exercise circuits. From first breath, you become immediately (hyper) aware of breathing patterns, rate, and force. Starts adjusting your mindset to focus on the breathing and let the rest of the workout to take care of itself. Only takes a few workouts to begin getting more and more comfortable using device. I will say, saliva output has definitely increased, but learning to control that more and more as usage increases. Tracking similar routes, efforts, etc. to see physiological changes for long-term benefit. Excited to see progress as the journey continues.
