on 13 July 2016
A very nicely designed product with gorgeous oled screen. This is the second pulse oximeter I have bought this week. The first one was from a well known high street box shifter. That one was around the £30 mark and was crude in comparison with an annoying pulse beep that you cannot turn off. It is the accuracy that counts though and I would say that although the bpm match each other the SpO2 is a bit different with the Contec reading maybe 1% higher on average. This is well within the +/- 2% spec. To get better than this it seems a Nonin and £100+ is required. They are both subject to occasional readings way outside what is expected so I don't panic if I get a very low/high reading - I just allow the unit to calm down. There is sometimes a reason for this, particularly bright light and sunshine so keep the unit shaded. I also suspect it may be affected by the cordless phone on my desk. Having the two units has been fantastic and it has given me great confidence. In my opinion an exact reading is not strictly necessary. In my case (copd) I need to know if I go sub 90% if I have a bad chest infection. I suspect if you wear the unit properly with the right environmental conditions and let it settle down for a minute or two and then (as the manual suggests) take an average of a few readings then an accuracy of +/-1% is to be expected.
A couple of other points - I had no problem installing the supplied software with 64bit Windows 7. I also found the manual easy to read and completely understandable - maybe it has been updated.
All in all, an excellent product and very good value for money.
