Bests & Worsts Reviews from Amazon

This is a worthless toy. Made out of plastic, the top cap had a broken plastic piece that prevent it from staying on. It doesn’t do much even when you try to exhale into it other then make a funny sound. It’s like being a kid blowing into plastic flute lol. It’s expensive, but I regret the purchase. Will not consider or recommend this product in the future. Cheaply made. Better to take herbal supplements or use saline/water for inhaler. There’s an OTC Albuterol substitute from Amazon that works better than this.
