- Oxy Respiratory Trainer | Breathe Easier with Stronger Lungs | Made with High Grade Silicone | Breathing Exercise Device for Lungs | Portable | Adjustable Resistance Settings | Black

Easy to use, comfortable, price and quality good

I feel more energetic climbing up the stairs

I bought this item since I vape and been having issues breathing. I think it was helping but it's hard to remember to use it.

Really impressed with the OxyBio breathing trainer. It’s easy to use and I can already feel a difference in my breathing control and lung strength.

Honestly this does not seem to do anything

La verdad pensé que sería algo diferente pero al momento de correr me lo puse y empecé a babear como un bulldog así que no no me gustó quizás si sea bueno para ejercicios pulmonares pero para deporte no creo

Great price. Cheaper than others out there. The quality is solid. The resistance range is not high but sufficient.

I tried this respiratory trainer, but I didn’t notice much improvement. Maybe I’m doing something wrong, or it just didn’t work for me personally. The device seems well-made, but I didn’t get the results I expected.

conseillé par mon I.A. je l'ai essayer et ça semble excellent aussi...

brilliant product.

very poor construction

It isn't the product that is advertised but clearly a knock off meaning the quality just isn't there and the ease of use is questionable as it has the rotating dial, however, does it actually work given the fact it isn't as per the advertised product so wouldn't expect it to live up to what is described in the listing

If you want what is on the image, don't buy this. If you want an overpriced, knock off chinese branded copy of what is on the image, with different packaging, go for it!
