Go2Sleep Device Failure - BEWARE!
As someone with very poor sleep hygiene, I purchased this $190 device with the intention of determining what my sleeping parameters were, and to hopefully correct any shortcomings recorded by the finger-worn ring. SleepOn Go2Sleep is described as "a smart, wearable ring that monitors your sleep and health data, including blood oxygen, heart rate, sleep stages, and breathing patterns". The data is then purportedly analysed by the SLEEPON app, providing insights and recommendations for improving sleep quality. Initially, I experienced major issues in attempting to pair the device with my Android mobile phone. After contacting SLEEPON, I was advised that the device's firmware was apparently out of date—despite its being shipped with that version of the firmware, and being relatively new. I then downloaded the new SLEEPON V.3 firmware, with the expectations of the device now functioning correctly. It then paired successfully with my mobile phone. However, after wearing the device for two consecutive nights, it stopped functioning; it would not turn on or register any data, nor show any sign of charging—these functions being indicated by flashing red and green lights (or not) on the device. Further, the data it did record in most cases was suspect as far as its accuracy was concerned. I checked my heart rate, and blood oxygen data from the (two only nights) Go2Sleep, and each was too high and too low respectively—in comparison to an SpO2 pulse oximeter I also use. In conclusion, despite many emails to the SLEEPON company, they refused to provide any sort of compensation, either with a replacement device of financial reimbursement as they stated (quite correctly) that my Go2Sleep was two months out of warranty. I asked for an 'ex gratia' payment as a goodwill gesture, but none was forthcoming. I can therefore not recommend either the faulty Go2Sleep device itself, or the dismissive, inflexible customer service of the SLEEPON company.
