I’m obviously dying and I’ll never recover, and I sleep poorly.

Craig it is definitely the alcohol, several drinks reduces your HRV which it calls stress and your sleep. The question is which do you prefer, great numbers on the watch or a brilliant red?

Yeah, you're saying it. Fanboys really are a huge problem 'cause the misleading information you get leading to false conclusions. However. I'm non of them. Still as a owner of Tac 7 BE: never had a Wearable Watch being that accurat as of Pulsoxy, Sleep, HR and so on. This said: sitll 8.37.How would I know that? Being an engineer I believe nothing and try to evaluate everything. Means: I used medical certified equipent to confirm and after that I was willing to accept the data T7 delivers. HOW IS THAT, when so many users tell otherwise? Since I'm not only an engineer but an developer I asked myself those questions. The pain point seems to be the way you wear the watch. The sensor on the back seems to be very sensitive to wether it fits just well, to slack, to thight. And there ist - at least for me - no way I can acieve this "just right" with a stock braclet. Especially for the tactix there is this nylon "bad ass" brachelet. Way to less flexible to adjust, all messurements way beyond reasonable derivation, Pulsoxy +/- 5%, this is bulls....I would feel my saturation way better. Not much better the silicon strap, it tend to be to tight...BUT: some small probably chinese manufacturer startig with a Y on Amaz... has those loop velcro Bracelet which you kann adujst to half a millimeter around your wrist and THAN you will find the exact adjustment of your watch for reliable data - meticously compared to medical reffernce equipment. Well why doesn't Garmin has a band like this? Good question, could save them a lot of trouble since the sensores are not bad. Possible point: double pack of those Y... Bracelets 22 bucks, Garmin Nylon Bad  Ass Bracelet 120 $. So it seems extremely important to find the exact fit. Than you find +/- 1% SPOx, and other data following suit compared to reference equipment. I stood flabbergasted - and no, I'm not a fanboy, the opposite is true: I was short before sending back the T7BE when I got the idea b/o with the braclets delivered, the data was...well not reliable.

Could please write the full name of those velcro bracelet starting with Y? Nothing will happen to you if you do ;)

Lol, I was drinking some Merlot earlier when I read this, I laughed hard enough that I almost spit the wine out.  

This stupid watch told me today that my body battery was at zero, I couldn't possibly recover in time because I exercise too much, and then sent me some badge telling me I'm a "well oiled machine" because my VO2 went up.  I've been wearing this watch for months and months, it's not getting used to me. Instead, I believe that the correct way to use the thing is to pay attention to the raw data and ignore the schizophrenic opinions of the software.

GTFO of here,lol.

Wasn't sure wether it'd be considered ok. The Brand is Yooside loop nylon, available in 22, 24 & 26 mm. Tried another brand too (Otopod), which looked exactly the same except there where triple packs available, but actually found these itchy. Stayed with the Yooside. Besides: its possible to fit two of those together an wear the watch near your shoulder but I wasn't impressed by accuracy when worn like that. Probably to much dynamic from Biceps.

If you have a few drinks any off-duty day (how often is that?), I'm not surprised it claims your sleep is bad. It does the same for me anytime I drink  a couple of beers (once a month?). Try not drinking any alcohol for a week to see how the status changes.

And yes, I agree with the Garmin - alcohol really ruins my sleep.

Thanks, I found them yesterday following your Y on Amazon... Quick question, how stretchable are they?

I have to adjust my original Garmin silicon strap during the day by two holes. Sometimes is too loose, then in the morning too tight... Not sure is it normal that my wrist changes so much. If Yooside loop nylon is stretchable enough, maybe I will not have to do adjustments anymore.

More stretchable than the stock silicone. Whether I have to readjust during a day depends on what I'm doing. T7 is a little heavier than nomal Fenix thus when being very active with your arms you might to have to readjust just b/o mass intertia.
