Vibeat Sensor Ring for OxyU & SleepU & Visual oxy & CheckmeO2 max

i have bought 2 aftermarket sensor rings and both have lasted about a year then start malfunctioning, cheaper than buying a complete new o2/heartbeat monitor

Works as it should good price and fast delivery

When it works, it is great. Had problem with sensing wire failed. Part replaced and now back to normal continuous monitoring.
Interesting physicians, nurses and resp therapist were interested in this design and function.

Also a good company that stands behind commitment to the customer. I had a problem with shipping, which wasn't their fault, but they stepped up and helped out.

So far, so good, Tracks data as well as I hoped.
