I wore five devices two nights and four the next three, on what ended up with some unusual nights, and below the results.<\/p>\n

\"\"<\/a><\/p>\n

<\/p>\n

I normally always sleep like a rock, but one night not so! And the night before I went to bed late (even for me)<\/p>\n

Unusual is nice for tests, so AI fakes just don’t invent stuff!!!<\/p>\n

But it just happened to be while wearing multiple devices for tests, so an excellent opportunity to do a comparison.<\/p>\n

The devices in question I all reviewed in here:\u00a0T8Ultra<\/sub><\/a>, H06<\/a>, U17<\/a>, ER08<\/a> (and R13<\/a>)<\/p>\n

They all do a quite good job at detecting the sleep periods<\/strong>, and even catching when I doze of in a chair and awake periods, but like for so many other devices, I would suggest to generally just ignore the rest of the claimed sleep-details – but perhaps the T8Ultra<\/sub> gets it fairly right.\u00a0In my experience the T8Classic<\/sub><\/a> was great at handling sleep, and so seems it successor the T8Ultra<\/sub>!<\/p>\n

 <\/p>\n

T8Ultra<\/sub><\/a><\/h2>\n

Durations right, details likely… It might<\/em> have missed if I dozed off early on the third, as the H06 below says, I’m not sure…<\/p>\n

\"\"<\/a> \"\"<\/a> \"\"<\/a> \"\"<\/a> \"\"<\/a><\/p>\n

But it is the clear winner of getting things what looks the most right.<\/p>\n

 <\/p>\n

Ho6<\/a><\/h2>\n

The H06 also normally gets the durations right, though it missed the second half on the second here, details looks fairly likely…
\n\"\"<\/a> \"\"<\/a> \"\"<\/a> \"\"<\/a> \"\"<\/a><\/p>\n

It is good at the periods, though it can have some inaccuracies in the wake-up end.<\/p>\n

 <\/p>\n

ER08<\/a><\/h2>\n

Durations right, not on the third though, details ‘meh’…<\/p>\n

\"\"<\/a> \"\"<\/a> \"\"<\/a> \"\"<\/a> \"\"<\/a><\/p>\n

 <\/p>\n

U17<\/a><\/h2>\n

One day completely missed, third way off, else durations right, details well just absurd!<\/p>\n

\"\"<\/a> \"\"<\/a> \"\"<\/a>\u00a0\"\"<\/a> \"\"<\/a><\/p>\n

 <\/p>\n

R13<\/a><\/h2>\n

Packed down, so only the first two nights included<\/p>\n

Duration reasonably right, details doubtful.<\/p>\n

\"\"<\/a> \"\"<\/a><\/p>\n

 <\/p>\n

Result<\/h2>\n

Generally they do a fair to good handling of the overall sleep period.<\/p>\n

Though the details of T8Ultra<\/sub><\/a> and the H06 both looks reasonable at first glance, they do not agree with each other…
\nBut note that the T8Ultra<\/sub> got longer deep sleep periods first than at the end of the sleep, and that is very<\/em> likely to be reality!
\nIt also correctly detected on the second night that I did not get up when I woke up, but rested\/rotated a bit.
\nIt matches my experiences with the old T8Classic<\/sub><\/a> that they do a really<\/strong> good job on sleep.
\n(please be aware that there is a generation of T8 between the classic and the ultra, and they do not<\/em> work quite as well, reviewed them here<\/a>)<\/p>\n

BUT details<\/strong> are hard, and even sleep clinics struggle doing them,\u00a0 so really not a surprise these tiny devices do not nail it, though some certainly seems closer to reality than others.<\/p>\n","protected":false},"excerpt":{"rendered":"
