Amazfit T-Rex 2 Rugged Smart Watch 47mm Military Certified Dual-Band GPS 24-Day Battery Life Ultra-Low Temperature Operation AI

I've owned this watch for almost a year now. Do I regret it? Absolutely not! This watch has literally changed my life. I'll just start out with the bad. IMO, don't buy this watch for sleep tracking. I think its sleep sensing capability is complete BS. My watch will regularly state that I'm sleeping when I am wide eyed awake at 3 a.m. in the morning. It's so unreliable, that it makes me doubt the entire smart watch industry for sleep tracking. It's a good thing I didn't buy this watch for sleep tracking because I would have been terribly unhappy. So why did I give the watch 5 stars? It's because everything else about the watch has been terrific. And considering it's affordable price, continued free application and watch updates/improvements throughout the year, downloadable apps, GPS tracking, heart rate recording, incredible battery life, etc., I consider it to be the best smartwatch on the market in this price range. The heart rate recording could be more reliable. I have been on the treadmill at times when I know for sure the heart rate sensor on the watch is not recording correctly. It's usually related to dirty (or sweaty) sensor on the back of the watch. But it can also be that I didn't have the watch tight enough or that it was in a strange position on my wrist. Cleaning underneath the watch, moving the watch location on my wrist, or tightening up the band all seem to help get the sensor back on track. It's an annoyance. But I imagine this is going to be the case with most every smartwatch brand and is unrelated to the actual watch itself. The GPS tracking is top notch! Love it. I also love the visualization on my hiking history on the included app. It will color code the trail based on the speed I was traveling when I hiked. It will also record and show my heart rate on a chart all throughout the hiking. The feature that's changed my life is the PAI capability. PAI (Physiological Activity Indicator) is an intuitive algorithm that evaluates multi-dimensional personal physiological data measured by the watch. It converts this data into a easy to understand PAI value or score. The score is based on the HUNT Fitness Study. According to the study, keeping your PAI above 100 will help reduce the death risk of cardiovascular disease, and increase your life expectancy. I have changed my workout to maximize my PAI score. And in doing so have lost 35 lbs of fat in the last year. I've learned a lot about my health, what was causing my lack of results before, and am thankful to the makers of this watch for opening my eyes to it all. Plus, I feel a whole lot better. In summary, for the health conscious, this is a great watch to consider. It's very tough (for outdoor sports and adventures) and long lasting (battery). If you are looking for a watch to help you track your sleep, ehh, better look elsewhere--not sure if sleep tracking is accurate for any watch. Read more

The battery, speed, features, durability, clarity, and accuracy are outstanding. You cannot beat the price and quality of this watch. The battery is as good as they say it is. If you use it constantly through the day for various things it will not last the full two weeks but it is still much better than any smart watch I’ve owned. I’m on day 3 now and at 74% battery using it a lot. I’ve fiddled with it through the days using it as often as I can. The OS is smooth and runs very snappy. Running a timer and the stopwatch while using a compass? No problem! Some of the free watch faces have the ability to allow you to go directly to various apps on the device or tells you what is running or if Bluetooth is being actively used. Too many features to go through in a review here but it has plenty of information. There are some watch faces that provide you with tons of useful information. Metrics, date, weather, moon phases, barometric pressure, rain warning, sun rise/set, alarms, screen lock, humidity, etc.. it’s a lot. It’s durability seems to be really good. It is plastic so it’s very light but still feels very solid. I haven’t felt like it’s going to break if I bang it on something (which I have and it is unscathed). The band I think is great but I did see where some people have broken there’s. No worries though because there are replacement bands through AmazFit and aftermarket; I bought an elastic breathable band and replacement was easy. UNSCREW THE LEFT SIDE (side with up and down buttons) ONLY! Otherwise you’ll strip the tool. It requires a special tool so make sure the band you order has the tool to remove the screws. Overall the quality is outstanding. Screen clarity, resolution, and readability in the sun is amazing. It will adjust screen brightness automatically depending on the lighting around you. Colors are vivid. And finally accuracy of the metrics for health and sleep seem reliable. I’m not a health nut so I don’t need it to be 100%. That said it tracks on par with Fitbit and various other watches I’ve used. The graphs and layout of information is very in depth yet easy to read. Sleep tracking seems to be very accurate and comes with an optional subscription to allow ai enhanced ambient sounds customized to your sleep pattern. It learns what helps you sleep better and shuts off at the appropriate time and uses a smart alarm the wake you up slowly within 30 minutes of your set alarm. So not to wake you abruptly. This is a game changer for the price and I’m grateful I chose to try out this watch. As long as Amazfit keeps doing what they’re doing, they have me as a customer for life. 5/5 stars! Read more
