### ⭐ LOOK ELSEWHERE
*by B***P on August 5, 2025*

After 4 years of tremendous service from my Amazfit T Rex Pro, it stopped working and it was time to get a new watch . I'm not the most demanding when it comes to my fitness data, I just like to have some point of reference to stay on top of my goals. What I need more than anything is a reliable and tough watch. The T Rex Pro was perfect, I could go from crushing a work out to working on my car without worrying if I was going to break my watch. After watching YouTube reviews and doing some research I felt pretty confident that this watch would be the perfect upgrade and for awhile it was. The watch felt hefty and rugged, the features were awesome, and the health data, while not the most accurate, was suitable to my needs. However, the first sort of red flag was the box. No company branding. This is probably some cheap drop ship product. Then after one trip to the beach, nothing serious, the battery life deteriorated to point that it would last more than 10hrs. Then the screen became unresponsive. After doing some more research, this time on Reddit I learned that I wasn't the only one having these sort of issues. I was very disappointed, because I do really like the look, build, and features that this device offers. lt cost about the same as my T Rex Pro which was an amazing device. But it simply put isn't worth it. Especially if someone wants to use the GPS features for hiking. Imagine being out in the wild and relying on this device for navigation only for it to stop working out of nowhere. There are better options out there and I can't recommend this to anyone.
