Works great, very compact, but didn't realize it needed to be cleaned with distilled water until read the manual. Bit of a hassle when traveling overseas.

This is a great product with wonderful portability.
This nebulizer is perfect for on-the-go asthma sufferers. Its portability and ease of use are exceptional. The only thing that would make it better would be for the mouthpiece to redirect toward the user. Medicare won't cover it, but if you can afford it, it's worth it! Would buy again!
Our doctor recommended recommended ultrasonic nebulizerI, We got this nebulizer 10 years ago. My son was 4 when we started to use it, and now he is 14. Although we had once in a while change the mesh which cost around 50 use, we used this product and very happy with it. It is an ultrasonic which means the nebulas are so tiny to most of the medicine gets into the lungs.
