Kospet Tank T3 Ultra VS Tank M3 Ultra: Which One Is Better? + All Features 

So much helpful bro for choosing the best one... Though the T3 ultra is not available yet in my country.. Hopefully it will be available soon. Waiting for T3 ultra Love form Bangladesh 🇧🇩 ...❤

I received my Tank T3 Ultra but unfortunately it’s not working, Blood oxygen, Heart rate, steps none of them work. After several reboots and resets no luck. The blood oxygen, heart rate kept telling me wear the watch properly but nothing work, I call customer service they told me I might received a defective item but I have heard too many complaints already, will pack it back and return it, I don’t want exchange, I was impressed when I saw the watch, the build quality is just great and looks great but I don’t trust their software which is sluggish and terrible, I believe you get what you paid for, this wasn’t my first smartwatch, I have an apple watch Ultra and a Garmin Fenix 7, was impressed about the look of this and it’s price was a lot lower than the others but I don’t think it’s worth it

What do you mean four VARIOMETER ??

In fairness, it does seem your review is based on your experience with a defective device. Also, your comparison to Apple or Garmin devices is not really applicable as these devices cost much more than the T3.
