It works as advertised, love it. Just be careful and dont get ahead of yourself. Take your time to get used to.

I’ve been using this training mask during my cardio and cycling workouts for the past month, about three to four times a week. I’m pretty familiar with this type of gear, and overall, it’s done a solid job to date.The adjustable resistance levels make it easy to scale intensity. I could change settings mid-session without stopping, which helped keep things flowing. The mask fits securely and doesn’t slip while I’m moving around, and it’s comfortable enough, even during longer workouts. That said, I’ve used a couple other masks that felt a bit more snug or better-built. This one isn’t far off, just not quite at that level.I started to notice better breath control after a few sessions, and I don’t tire out as quickly on regular runs. It’s also easy to wipe down and keep clean. If I could rate it 4.5 stars, I would. It’s a great option if you’re looking to push your breathing a little harder during training. If you’ve tried other masks before, you might feel the difference, but for most, this one will do the job well.

Good

I returned this mask because it was too big for my face and I found it difficult to put on along with my vision glasses. Addionally, it does not really simulate breathing at high altitudes. All this does is limiting the air flow.I didn't think it was different from a regular mask. I just wish it was labeled differently.

It met and exceeded every expectation I had

I’m training to climb Kilimanjaro this June. I bought this device 8 weeks before my climb to ramp up my training. Is it restricting my breathing? Absolutely yes! It comes in a nice case that I can easily attach to my pack.My only complaint is that it gets so wet from the condensation and moisture that are expelled from my mouth and nose while breathing. I have to take it off and dump it out at times. Otherwise, it’s great and I’ll continue to use it until I get the real altitude in Tanzania.
