20 years on cpap and this is a great exerciser as I attempt to get off of cpap

Meh quility you get what you pay for if your buying it cause you think it’ll make you more attractive it won’t but it does what it needs to but the slider isn’t the best not that much control it only has like 4 pre set settings

Son de utilidad y buena calidad

Absolutely did not work.

It does work

I have to rate this product 3 stars due to safety concerns. This production should ONLY be used for exhaling, not inhaling. Upon inspection of this product, I noticed a screw inside of the device that is a potential choking hazard. Please ensure this piece is secure and you only use this device to strengthen your expiratory muscles.

Dubious. Not well built. Waste of money.

As a runner, I found this product very impractical. The biggest issue is that sweat and spit quickly block the vent, which makes it difficult to breathe and eventually defeats the whole purpose of using it. Despite the claims, it does not serve well for performance enhancement during active workouts.The design shown in the images is misleading – these trainers are not suited for running or any high-intensity activity. They may only be somewhat useful if you are sitting still in a dry or cold climate and doing light breathing exercises.For actual training benefits, I would recommend going for a breathing resistance mask instead. The only challenge there is the higher price, since no reliable manufacturers are available from India yet.Overall, this product is not useful for runners or athletes. It’s more of a gimmick than a practical tool.
