Inhale Respiratory Trainer | Compact Lung Exercise Device with High Grade Silicone | Carrying Case Included | Breath Trainer with Adjustable Resistance | Portable & Easy to Clean

I bought one for myself and my boyfriend. I am on a club swim team and my boyfriend trains for marathons. We love this product. I tend to use it in the mornings and evenings. I can take deeper breaths. It has helped with my swimming especially with my flip turns and staying underwater longer. My boyfriend said he can feel the difference as he runs also. We love this product.

It is a great idea for stamina the only thing is you need to turn it to the plus to go to the easy setting and to the minus sing to the hardest setting

This Inhale respatory trainer has made a difference in my breathing during training and I've noticed my abs feeling stronger.

TLDR: Decent quality material and construction. Mouth piece a little bit thin. Bi-directional resistance dial for customizable resistance both ways. No physical instructions. The mouth piece is a little thin but overall construction is decent with a resistance dial on the end. There is a card with a qr code for instructions but no instructions in the box. It should be washed before and after each use. Nice storage case. No information on durability yet.

Works as good as advertised! Stick with it!! Recommend!!

Great idea, it’s like a compact elevation mask. It just needs reworking in the lab. Mused and others have mentioned, spit falls a lot from these. Back to the lab guys

Well-made and easy to use.

they work great
