Works as expected. The item on the store comes with wifi which adds $75 to the cost and is of questionable benefit... I'm guessing so your doctor can access your data?
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.
