The out-of-the-box experience was not antwhere near complicated at all. Installed the app on both an Ipad and an iphone, and can retrive data from either one the following morning (Only on has to be near the ring device overnight). Nice, informative and easy to use device. I like this and recommend it!

I thought this looked cheesy at first. But after reading reviews, I decided to try it. I have an Apple Watch but was getting tired of juggling charging for sleep use. This works great and has a lot more info than the watch. Have not tried the fingertip holder because they all seemed too big for my small fingers. The ring works great. If you dont want the fingertip holder, get this on their website because its $89 with just the rings. Recommended.

The first one got ruined because I did not follow directions, follow directions and it works great. My second attempt it fit great and the air holes are still in the mouth guard. It's definitely helped with snoring and opening up the passage way.

I did re-mold it 3 times to get just the right fit for me. And I will say that you should be careful not to bit down too much when molding it. My wife has confirmed my snoring has lessened dramatically and when I do make some snore sounds, they are much less harsh and loud.I say, give it a try. It does not appear to be returnable, but I think that reflects in the price. I think it will work for many people out there.

I have a very expensive dental device ($1800) for sleep apnea that broke after 1 year and is being repaired. It kept me from snoring. While its being repaired I tried this device and quite frankly it works just as well as the dental apparatus. It looks small when you take it out of the package but like someone else who provided a review I grew up playing sports and had to have mouth pieces like this every year, You just need to be careful when molding it to your teeth, You must spread the sides wide enough to place it in your mouth, then finish molding it . Also be careful not to bite down very hard and collapse the spacing between top and bottom. I am 65 weigh 230lbs and have a large mouth, because of my experience in sports I had no problem, Im actually glad its so small it makes it less invasive. I gave it 4 stars because the instructions did not address the molding process very well. As far as performance its definitely 5 stars for the money it cost!

I have already bought it once but it was lost and I had to buy it again. I really like it because of the size and the basic functions.

I bought this to monitor my SpO2overnight because I have breathing issues.I like the product and the information it has provided has been VERY helpful to me and my peace of mind. The product seems well built and has worked perfectly.Before you use this over night, take a few minutes to test the finger position of the device.
