I hope your not dissapointed when you get the watch...I had to return mine as gps was way way off and compass was 90 deg off also. Other that that it was a fantastic watch..
This is a great review. I've had the kospet tank t2 for awhile, its terrific. But after viewing this, I've already started the process of ordering the T3 lol
No storage or ability to play music from the watch alone is a deal breaker for me i love not needing to bluetooth a phone to a speaker and storing music on the phone from my own collection or the likes of Spotify premium downloaded stuff.
I own M3 Ultra, Amazfit Bip 5 (cheaper) and Amafit Balance (more expensive). In my opinion, M3 Ultra has much better build quality, screen and water resistant rating / Military rating than Bip 5, even Balance. However, even though bip 5 is cheaper, but it has better sports feature, especially for a runner. Feature wise, Amazfit Balance of course in different league. So, it depends on your need. If you rarely use sports feature, then M3 Ultra is a good smartwatch, maybe the best build quality in this price range.
