KOSPET Tank T3 Ultra Smart Watch for Men GPS, Extra-Long Battery, 50M Waterproof, Stainless Steel Unibody Rugged Smartwatch with Bluetooth Calling, 1.43" AMOLED Display, Pressure&Altitude&Compass

I received my watch on the evening of 08/13/24, charged it, set it up with the app on my phone, & set settings to not communicate notifications of text/calls/emails. It is solely used as a health/exercise tracker & watch. I do not have it set to always be on, and have my screen time set to 15 seconds.It is now 08:20,US Mountain Time, on 08/21/24, with my battery life at 86%. There are MULTIPLE reviews stating the battery life does not live up to the "as advertised", but I beg to differ. Different settings, Different allowed uses between the watch and phone, etc, cause a large difference in the battery life.I think, with having the minimal communication between the watch & the phone, & leaving the default mood/stress readers as "off" (I do not, as I was curious about this feature), it could last the maximum time as advertised.This is my 3rd smart watch. My first was not researched prior to purchase, and the sweat from working caused it to shock me short the watch. My 2nd was a CK30 which lasted 3 years and 3 months prior to the battery having issues due to diving too deep in the ocean. My first one had to be charged every night as I had it connected for notifications. CK30 only needed charged every 12 days without being connected for notifications.So far, Tank T3 is on day 7, still in the 80's%, and is my favorite watch! The weight feels great on my wrist. The step feature, in my opinion, is better than my previous watch by far! There may be a customizing option, but I haven't looked into it as of yet, but there is one thing I like more about my previous watch. The power button could be tapped once to illuminate the screen, and again to darken it. This one, the 2nd tap brings up the menu, and you have to let it timeout in order to darken.This watch has SO MANY FEATURES I am not used to, and I'm still trying to figure them all out. This is a great watch, & I would recommend it! Again, just remember, "as advertised" says "UP TO 30 days", meaning that your settings & phone to watch communications will lower the battery life. Some more drastically than others. Also, if you have notifications allowed to appear on your watch, think of how many notifications you get, as this can be a factor too. 100 texts/day vs 500/day. Also, if you play music through your watch (I do not, and have not tried the speaker out yet), remember that using a device's speaker instead of an alternate one can also drain battery life more quickly.I hope this review helps! This is my own opinion from my personal first week's experience. I have 0 complaints!UPDATE- 09/11 (28 days owned; 27 used):My watch, with all previously mentioned settings, just reached 39% battery life today at 3:40p US Mountain Time! I have used that flashlight feature 4 times, for an approximate calculation of 20 minutes total. I still have not used the always on, nor have I allowed it to play music or connect to my phone notifications/calls.

I was very pleased with the service provided. I had purchased the Tank T3 Ultra because it would give heart rate and blood pressure readings. However, the readings were not accurate which lead to my dissatisfaction. Amazon Customer Service were understanding of my concerns and made a generous offer for me to keep the watch plus a full refund. Which I did receive the refund. The action taken by Amazon was totally unexpected and well appreciated. Thank you!

I think this watch is much better than my last, which was an amazed fit GTR 3 Pro.As with all smart watches, it can be a kind of a pain to set up at first.You're always digging for permissions to turn on.As far as battery life goes it does drain a bit faster than I anticipated with all the health monitors running at hour intervals.The amazfit had it beat there.As far as functionality and responsiveness goes, this watch is much faster than the Amazfit GTR 3 Pro.The only problem with functionality is with the screen protector in place.It makes changing watch faces via long hold rather difficult at times.I have to lick my finger and rub it to warm it up to get it to work, and then it's still a bit laggy.Without the screen protector, it functions flawlessly and immediately.I'm not sure if a screen of protector is really necessary on this watch, but I didn't want to take a chance.As far as all the other functions go, they work fine with the screen protector in place.Swiping up, down, sideways all works flawlessly.One thing that bugs me, and I'm not sure I have it figured out completely yet, is the fact that when I use the assistant feature, for some reason my phone has to be active and unlocked at the time.This doesn't make sense to me, as my Amazfit assistant would function whether the phone was locked or not, but then that was not always reliable.Sometimes the Amazfit assistant would completely disconnect itself, but when it was connected, it would function, phone locked or not.The screen protector not was not lint free under the protective barrier from the factory.My work area was completely clean and free of anything when I applied it, so it didn't pick anything up statically in the process.I had to pry the screen protector back off when it wouldn't seal completely without bubbles and pick one piece of lint off with my pocket knife.I was able to use the alcohol pad and the drying pad to fix it and it was still able to stick to the display, however there are a few other micro size pieces of lint that I was unable to remove and they do show up when you shine light directly on the face of the watch.Otherwise, they're unnoticeable.This watch is unable to store music which is not a deal breaker, but my Amazfit was able to.There is a media sound on or off function with this watch so you can either play audio through the watch or through your phone.Connectivity is very good.I was able to remain connected at a distance of almost 40 ft with one wall in between the phone and the watch.I tested this by downloading a watch face.There is one guy on YouTube that gives the swatch a bed review.This is simply because he doesn't know what he's doing.Although you have to be patient, as with many other smartwatches, you can get this watch working quite flawlessly.Everything on it functions perfectly other than the blood pressure monitor, which is to be expected, simply because there is no cuff involved.Blood pressure cannot be accurately measured with light sensors with current technology.It will give you a ballpark figure but I wouldn't totally rely on it.Would I buy another in the future?Definitely!
