It worked, but was a challenge. The instructions on the website do not match what is on the app. Example: “enter shipping address” - but this does not exist on the app. They then sent a text with a link to an instruction video. The video does not exist. The equipment return form for asks for duration of the 2 tests. Don’t ask this after the fact, no way to know. Someone in the company needs to try it as a patient, get the long list of snafus, and fix them.

After reading all the reviews, I was anxious about finally starting my sleep study. A friend of mine who had used Blackstone for a sleep study a few years ago had similar experiences to what a lot of the negative reviews here have described. However, I was pleasantly surprised to find the app very easy to use. Perhaps they have made some necessary changes. The instructions that came with the ring were very clear, connecting the ring to the app was very straightforward, and the app was very clear about what it was doing, and what I needed to do. It was basically put the ring on my finger to turn it on, it connected automatically to the app, and immediately started reading my oxygen level and pulse. There is a very clear instruction at the top of the app that said “This is the first night of your sleep study. Press this button to begin,” and when I did so later that evening it started recording. The button that had said “start the sleep study” changed to “submit the sleep study” as soon as I started recording, so when I was done in the morning I just tapped that button and it said uploading data with a status bar. When that was complete a few seconds later, it said you have completed your first day. You can take off the ring and when you’re ready to start your second evening reopen the app. Everything again was very clear. So I think they have improved their stuff.

Absolutely horrible company. Sent the test without checking to see if anyone would be home or if I was ready to take the test. I was out of town when it arrived. Then they immediately started calling asking why I didn’t do the test the night it arrived, threatened to charge me late fees for not immediately returning the equipment, and ultimately threatened to charge me $1,500 for the test equipment if I didn’t take the test immediately and return the equipment. This was not weeks later, this escalated within the same week it arrived while I was traveling for work. Then, when I did return home and could do the test, the app would not stay connected and kept turning off every time my phone went to sleep. Ended up having to lock my screen on all night to get the test to stay connected. Then after returning the test they wanted me to pay out of pocket instead of billing my insurance. Threatened to turn me over to collections if I didn’t pay immediately. I guess they didn’t want to wait for the insurance check. Absolutely horrible experience and the worst company to deal with I have ever experienced. They call back to back all day long. One day they called 36 times while I was in a meeting with clients. This was just about my results. This is supposed to be a medical testing company - I wasn’t signing up to be a test dummy for collection agency tryouts! Extremely aggressive company tactics and they use harassment to make you bend to their will. DO NOT get involved with this company for any reason whatsoever. Make your doctor choose another provider for your test. Any results you can gain from the experience are not worth dealing with them. There are other options - don’t do it.

Problems connecting app with device. Restarted phone a couple different times, turned Bluetooth setting off then back on. Once it finally connected, the app stated the ring part that you wear on your finger to measure your O2 levels and BPM was off and needed to be put back on. I kept adjusting it, then it would finally work again and then it would stop again. I had it on my thumb, which is my biggest finger like it says. It says not to use your middle finger so I had to put it on my thumb and it was still basically loose. Not a pleasant experience. I spent over an hour trying to get it to work before giving up for the night.
