I’ve tried every home sleep test and this one is the best. There is a device with a bulky head band, one with a chest probe and a finger and wrist band, others with lots of cords and wires and nasal cannula and chest straps. You will never find a home sleep test device that is so comfortable and easy to use like the sleepimage. It’s just a ring on your thumb. It is the best home sleep test device on the market and has been featured in over 100 peer reviewed articles. More than any other home sleep test device. The data and accuracy is impeccable. All I needed was my smart phone and a ring on my thumb. This product is a game changer in the industry. Highly recommend over any other!

I’ve been wearing an Oura ring and an Apple Watch for years, so my standards have grown but I tried this ring for 4 nights per a doctor request and it dramatically reduced my sleep quality, just wrestling with the giant ring all night with its bright lights as I moved around. The first night, I had insomnia and woke up at 1am, which hasn’t happened in as long as I’ve been recording my sleep. By the end of the study, I removed it at 4am and gave up. The app sync was constantly buggy and lost at least one day of data—but the app doesn’t show the end user the data so I couldn’t even get full visibility into it until meeting with my doctor. A disappointing process entirely when my Apple health data would have worked just fine.
