Like you said, "Everyone is entitled to their opinion". Anytime you state numbers like are shown in the graph in the above post, 75% of 85% is marketing games. Why? Because if they said outright that their unit has an accuracy rating of <64%, not many people would buy it. Those numbers (75% of 85%) are their own numbers, not ones I pulled out of the air. Then, you have to consider, when a company is in business to sell a product, they will sometimes skew some numbers in their favor. The unit runs off a human designed and interpreted algorithm, so it can only be as accurate as the info fed into the design. If the information fed into the algorithm is flawed, then so are the results.
In #4 above, We don't measure movement, breathing, etc.
and can't pick up sleep disorders. We all know that the brain waves of someone with sleep disorders, is a lot different than a normal person. In #5 above, they use a single channel sensor, where I believe PSG uses at least 3 channels to measure brain waves and eye movements.
Basically, what they are saying is we can tell when the brain has went into a deeper sleep because of the Delta wave activity, and that is about the gist of what the unit does. The rest of the time is just a guess at best!
If you listen to the video, they have run 3 internal studies,
internal, meaning they can come up with results that fit their needs. In the above study, they studied
10 people, of which 4 were females and
all had no sleep complaints. Again, I have to question the validity of their studies. Ten people is not much of a sampling, and again, did they only test 10 people, or is that the 10 best results they pulled out of the test? And why not test it on people with sleep problems? He even states in the video, that when he used it, his test come back at 99% accurate, but that other peoples test had come back as low as 25 to 30%. That most people would fall within that spectrum. I'd hate to think, that I was relying on this device to give me an accurate report, but that I was one of the fortunate ones that was at the 25 to 30% range, and I have no way of knowing that. If the device is as good as they state, 90% accuracy on determining sleep levels, how can it only be 25 to 30% accurate on some people? If the algorithms are programmed correctly and accurate, there shouldn't be people down in the 25 to 30% range.
Artificial intelligence (the secret ingredient) a computer program written by a human that uses formulas that is input into the software. If the formulas are inaccurate, so are the results! It needs to be tested more thoroughly, to test its accuracy!
I'm not saying it's a worthless device, I'm saying not to rely on the results as gospel! Several people are saying the device is showing that they are getting the restful sleep they are supposed to get, but they still feel tired. It could be that they are not receiving accurate information! Others say the information is very accurate, how do you know this? Because you wake up feeling good, even people with untreated OSA wake some mornings feeling good! I just want people to go buy this device with their eyes open, and not think, "It will be accurate for me and I can believe everything it tells me". Personally, If you have the extra money and the cost is no big deal, go for it! But, if your on a tight budget, I would recommend you save your money! Most trials out there pay you something for your time and provide you with the products needed for the trial. But, ZEO has people buying their product and using them as guinea pigs to get their feedback about their product! Kind of reminds me of those black 8 balls people bought years ago, you ask it a question and turn it over for your answer! Sometimes it's right, sometimes its wrong!
