Works Well, November 9, 2011
This review is from: SFO Medical RMO Finger Pulse Oximeter. SpO2 (Oxygen Saturation Level), pulse on OLED display, adult/pediatric FREE SHIPPING, FREE CASE, SFO Medical Pack (Health and Beauty)
I looked at many of these. Don't have a medical requirement but just like gadgets. I read many reviews, and its funny how many people say every model is "accurate" and that they "read the same as my doctor's office." Let me tell you my experience and why this just isn't true.
First of all, these devices read pulse and oxygen saturation, with "normal" SpO2 readings in the 95%-100% range, but no less than 90%. That is a pretty narrow range, and if you read the specs of these, most have an accuracy of +/- 2 or 3 digits. In other words, if your SpO2 is REALLY 95%, they may read 92% or read 98% and still be in their stated accuracy.
I have four of these devices, this one and three others from different manufacturers. Since I have 10 fingers, I can test them all at once, and guess what, no two read the same. My four will typically span a 4% range. Once may read 93%, one 94%, one 95%, and one 96%. That's a pretty wide range when the "normal" range is only 5% wide.
So I really caution people about believing these cheap devices are accurate. They are generally consistent, but I don't call them very accurate. Find your normal values and use those as a guide. Of the four I have this one reads in the middle, so that is a good sign, but I have two of the same model for a different one and both read differently, so even with a single brand, it appears there is variations.
Maybe even more interesting is the pulse values don't even match across different models. You'd think that would be cut and dry and it wasn't.
So in summary, these are a good guide, but not a perfect device, so use them as a guide, and acknowledge their weaknesses.

Item is good service is poor, November 16, 2011
This review is from: SFO Medical RMO Finger Pulse Oximeter. SpO2 (Oxygen Saturation Level), pulse on OLED display, adult/pediatric FREE SHIPPING, FREE CASE, SFO Medical Pack (Health and Beauty)
The item works well. The write up about getting the free case and batteries included is a myth and you can't contact Amazon or the vendor as they have protected themselves from anything other than a product return. Just for being complete, the listing says that the unit takes two AA batteries that are included. The unit takes two AAA batteries and they were not included even thought they were pictured and mentioned in the listing. Someone at Amazon better start checking the vendors compliance.

RMO is an excellent finger pulse oximeter. Its reading is very accurate and display is very crisp. It is nice and good looking oximeter. It is very light and very portable.
