Thank you received in a good perfect time and thanks for AliExpress fast delivery
I was so excited to find this portable nebulizer. My husband has asthma and I am getting over the flu. This unit is smaller than we thought. It is so quiet which we love! We put colloidal silver in it and started using it. It is amazing!!! The mask is a good fit and you can put batteries in it which makes it easy on the go. We are so happy with this purchase and are feeling better!
