Cheap product doesn't give you a fresh clean smell after the mask has gone through its cleaning cycle. Even after all the items had been replaced.
Used the battery once and it worked as advertised.
My order arrived promptly. There was an error that was rapidly corrected. I would highly recommend this merchant.
Arrived quickly and accurately.
Very compact and lightweight does take some getting used to.
Works well. Very comfortable nasal pillows. A bit louder than standard but I knew that before purchasing.
