My unit doesn’t work My unit doesn’t work. On the heart rate on of the digits partially works. Half of the number is cut off. It constantly beeps as well. I would not buy this again. I am going to email company for refund. Another issue there’s no contact info PD return info in the pamphlets that are with the item. A totally waste of money. I would give it ZERO stars if your rating bar would have given me that option. A 1 is to much. Unit totally unusable!

The unit is very attractive and quiet! The unit is very attractive and seems to work fine. So far, I am impressed with it.

So far so good So far so good. Attached to BPAP hose. Came quick. Easy to set up and use. Seems to be well made. I just use the outlet for oxygen at night and don’t use the timer. Set at 88 and mid range .

Oxygen recovery therapy The unit is almost perfect except for the oxygen concentration levels at higher liter/minutes decrease significantly. So anything above 3 liter/minute reduces total oxygen per breath cycle. But at this price it’s great.

This company is just a scam This company is just a scam. My machine was not at all what they said it was. Then they are giving me a hard time about returning it. I will never order anything else advertised on Facebook.
