More than useless, and dollars down the drain.
So this Lung Inhaler is going to be one of the greatest lung and breathing products ever!!..... Ha Ha! Would give zero rating if I could. When it FINALLY arrived, what a useless piece of kit this was. Horribly overpriced for what arrived and I can't even find it in their product listing (bears no resemblance to what I thought I ordered), and when I used it, even more underwhelming in its effectiveness ( gave it 3-4 weeks). Spent $79 for 3 plastic nasal inhalers, and honestly, I'm getting more nasal relief from a $6 Vicks nasal inhaler. Three words - steer well clear.
