KOSPETTank M3 Ultra Smart Watch with GPS, 50M Waterproof, Compass, Altitude, Air Pressure, 480mAh Extra Large Battery, Full Stainless Steel, Bluetooth Call, 1.96'' AMOLED Always-on Display, AI VoiceCarbonfree Certified

I originally bought another similar smartwatch for my son, who was impressed by its functionality, and eventually decided to get one for myself as well. After two weeks of use, I can say this watch delivers on many fronts, especially in terms of durability and battery life. My overall rating has gone from a solid four stars to five!What I love most is its durability. After two weeks, the battery is still at 53%, which is outstanding compared to my previous watches that required charging weekly. This alone makes it a clear winner for me, offering a hassle-free experience without the constant need to recharge.As for water resistance, this smartwatch performs much better than my last one, which would often malfunction after contact with water, requiring a reset. With this new watch, I no longer need to remove it when taking a shower or during activities involving water, which is a big relief.In terms of functionality, I appreciate that it does the basics well—time and date visibility are clear, and the display activates when I raise my wrist. However, if you're looking for advanced, flawless integration with an Android phone, it may not compare to high-end Google or Samsung watches, or Apple watches, which tend to be better optimized for seamless functionality. For the price, it meets my needs just fine, but it might not be perfect for those expecting high-end smart features.My only gripe is the strap material. Initially, it felt like cheap plastic, which was disappointing. However, after using it, I found it more comfortable than I first thought. While I initially wanted to dock points for the feel of the strap, the watch's other features have won me over and helped balance out my overall impression.If you're looking for a durable, waterproof smartwatch with excellent battery life, this is a strong choice. Just be aware of its limitations when it comes to high-end functionality and materials.

UPDATE: Customer service is second to none! After speaking with them, they are EXTREMELY helpful and put the customer first. You won’t have buyers remorse if you purchase one, but if you have issues, reach out to KOSPET, they really want to take care of any issues you have with the watchI didn’t take any pics because the watch looks EXACTLY like it does in their ads. Just under 2 weeks with it and it looks brand new out of the box.Pros:Great battery. 7 days and I’m at 47% battery life, very impressive compared to my Apple Watch. Love the watch face options, I have 0 complaints on the options. The watch materials are SOLID! Very durable. Easy to use watch and the app is user friendly. Find my watch works great.Cons:Doesn’t track steps properly. I have not taken the watch off in 7 days, and there three days where none of my steps were tracked. Heart rate doesn’t work very well, it just won’t read a heart rate. Disconnects from the app pretty often, it’s a little frustration but could get over that if everything else worked better. Find my phone is more of a joke than anything else. The phone does not alert, and the screen reads “IPhone found”. When I click Find my phone, the watch vibrates and makes sound and the screen shows “IPhone found”. Find my watch works great, but not finding your phone. The rubber watch band feels cheap, you’ll want to get a different one if you order one.KOSPET has something’s to work on for sure. I could probably get over most of the cons if the find my watch function worked. When I’m alone, I have a habit of setting my phone down and forgetting where I put it, and this was one of the major pros to the Apple Watch. I will be sending this watch back and look for something that works better. The watch looks great, it is durable, but the pros do not outweigh the cons for me.

To me this is a great looking watch. Connecting and syncing was simple. Tracks activity well. Shows walks and runs on map using GPS. I do wish it was Google maps as you could switch to satellite view. A little buggy when it comes to showing messages etc on the watch as it sometimes mixes up the 'header' and message body. Love the 4 buttons vs a dial to switch between menus etc. Wish it has additional watch faces. I did have one issue when the watch face was totally dark one morning when I went to take it off the charger. Had to do a "Manual Upgrade" to the system. This happened two days ago but seems to be functioning fine now. A good functioning watch at a great price. Would recommend.Update 6/10/25:Had to 'reboot' the watch again. This time it was stuck with a watch face, vs just a black screen. The time was a couple hours old and not changing. I pressed the 'BACK' and 'SEL' buttons together until the watch rebooted. I also did a 'Manual Update' too. Watch working well since then which was 2 Days ago.

After less than a week of normal use the screen went black, it was at around 40% when this happened, the app says the watch is dead but it will not charge. For $120 I am very disappointed. Before the watch completely failed I also noticed the battery life was all over the place, after the first couple days of use it would use maybe 10% battery per day, after that it used about 70% overnight while not being worn. On the last day it functioned it completely stopped reading steps and the weather location was way off. I would not recommend to anyone, this is a very cheaply made watch being passed off as a “heavy duty” or “military grade”. Judging off other reviews it seems the watch is pretty hit or miss on weather or not it works correctly. Do. Not. Buy.
