Amazfit T-Rex 2 Rugged Smart Watch 47mm, Military Certified, Dual-band GPS, 24-Day Battery Life, Ultra-low Temperature Operation, AI Fitness Coach, 150+ Sports Modes, for Android iPhone(Black)

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.

First of all, I love the ranger green color, it is definitely a favorite color of mine.This watch has performed so so well. I enjoy being able to track my steps and sleep. I am surprised how accurate it was with my sleep time and when I had to get up during the night for when my son or puppy woke up.This watch is surprisingly durable. I have smacked it on the corners of countertops, door frames, etc. and there is no scratch on it!!! I am thoroughly impressed with it.I did take it into the shower which had no issues, but the problem is moisture gets stuck in the crevices of the band so it's hard to thoroughly dry. I would just take it off before you get in.Now the battery life, it is amazing!!!! I love having a watch that I don't need to worry about the battery life. I typically get 20 days (5% a day) so when the low battery notification comes on at 10% I have 2 days to charge it. The watch also charges up to full in like 2 hours.This watch is perfect for me. It looks awesome. Works great absolutely no issues. Battery life is phenomenal. Great features on the watch. I would highly highly recommend purchasing this watch if you are looking for something like this.

Great watch, truly is water resistant, for all the events I enjoy it life. Mostly life proof at that too. I'm a huge gshock fan, tried and true. This watch fit my expectations. The battery life isn't even remotely right. I think the only way you get the 20 days is if you take it off and don't touch it. Only on Standby. I exercise or run or something the heart rate tracker comes on and stays on, which devours battery life. I will likely turn the auto exercise off and see how long it really lasts, since right now, with that active I only average about 7 days. I exercise daily for a couple hours each day. Not counting the rest of movements through the day.Watch came with regulations in pretty much all languages. The manual was non existent. I had to look one up online to get it to shut up about idle time. I wish the watch had a 1 button lock. Instead of a menu slide then find the lock icon.The app is fun at first, but then you tinker with it a bit much and it seems to have some spots where there are issues. Nothing major, just odd locations for certain things when you hunt them down. Otherwise, mostly user friendly. There is a lot, a lot, of stuff in the app and on the watch. I am still working through everything a couple weeks later.All in all, definitely worth the money, battery lasts longer than either of the big companies, still. App has a bunch of stuff, only thing I can't do is call, and that may just be a permission thing that I haven't found yet.Note: lock the screen before washing hands or shower or even getting in the rain. Water will flip the menus and stuff.
