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 .

DISAPPOINTED: DISAPPOINTED: The Pulse Oximeter works as expected. However, cannot access the app. Have tried to contact company for support but their email does not even work. For me, the main attraction was to be able to use it with the app.

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.

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!

You get an extra charge because it comes from Canada Machine works, well packed, you do have an extra charge that I did not know because it is charged in Canada. They should also include a longer cord.
