Review: Amazing 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.
Review: A great watch for an average user - I’ve been using this watch for about 4 months and so far I really love this watch! Its not perfect and I’ll point out the flaws but it definitely has a lot of pros that has made me love the watch. Lets start with the cons: - sometimes it looses connection to my iPhone 13 and ill have to either restart the watch or restart my phone to reestablish the connection - The watch face store isn’t the best, I can’t find what I favorite and one of the purchases I made can’t upload the face to my watch - Very important: some watch faces consume too much battery due to animation they play or all of the information they display. This isn’t disclosed when you purchase The watch face which i wish it was because the battery life is important To me. - Cant answer emails, can only read. - Does not make any noise, only vibrates - Can’t answer calls, you only get the option to decline the calls The pros: - battery life!!! Pay attention to the watch face you choose because some of them say that they are battery intensive. Longest I’ve had the battery last on a normal watch face is 24 days! Vs 17 days on a battery intensive watch face. - Its very sturdy and solid. Ive banged it against hard places a few times and have not damaged the watch at all. - Waterproof. I’ve showered with it, and gone swimming both in a pool and in the ocean and it works perfectly. - The functionality. I work in the IT world and the functionalities work fine for me. I use the vibration to wake me up, (very strong), I use the notifications to read emails and receive calls, I use it to check the weather, I use the steps, and i check my heart rate. For the average user, it gets the job done perfectly. Over all as an average user, I’m extremely happy with my purchase. I never used an apple watch so i cant really compare it. I’ve had some hybrid watches and i would say this watch is far superior in comparison to those.

### ⭐⭐⭐⭐⭐ Great value quality & overall functionality for a heavy duty fitness smart watch.
*by C***Y on July 27, 2024*

I chose this watch (TRex2) after looking through all the different options with Garmin and apple watch then finding the Amazfit product line and comparing the models. Not only does it make my lil T Rex mama heart happy that its a TRex product but it also boasts overall military grade durability, extreme cold/hot resistance, water resistance up to 100m and 10ATM (big issue for me as a active swimmer and being out in the elements daily with my life/job) & dirt resistance. The display is vibrant & it has the touch screen as well as button access which was important to me as I had a versa fitbit3 that would sometimes not respond to touch if I was sweaty or it was wet from swimming etc. on top of all of that it also has military specs and durability - important to me (will update on this in future) the watch band it came with Stock is actually surprisingly flexible but strong and itsnt too bulky at all - it nests comfortably against my wrist and has two band holders built in to hold the excess strap. I have great expectations for this band lasting as its not too rigid but feels strong. The screen itself is smooth and slightly dropped down to protect it from getting banged up on. ( I did however purchase a silicone face cover and glass screen protector’s to allow for extra protection - I am very active daily and didnt want to have to worry Id smash the face on something ) the fitness functions are intuitive and recognize your movement fluidly. As for the sleep analysis it seems to be accurate and tracks shorter periods of time with a easy to grasp breakdown of sleep quality. It’s important to me that the TRex2 also tracks stress and heartbeat/BloodO2 & breathing patterns. The Zepp app is relatively easy to navigate and with a little exploring - I was able to go through most of the functions within minutes of set up - which was extremely easy to pair with my iPhone. The watch came with a 54% charge and the instructions reco that you fully charge it before use. It was at 100% within a half hour. I also like there is a security function that allows you to set a 6 digit passcode for when you remove your watch - this activates immediately upon removal from your wrist - but I really appreciate this function as there have been times I have taken off my fitbit and it was lost/stolen and I worried about my data safety. I have already slept with the watch and enjoyed the sleep report. The auto dimming functions and overall screen brightness is impressive- I can also appreciate the lift to wake as it’s intuitive to your movement and doesn’t turn on/off everytime you move your arm. There are countless faces available - free selections are very nice as well as offering some paid faces - I spent over an hour looking through them all. There is even a “flashlight mode” - the screen goes ery bright cool white and would be good to spot something dropped or to move through close quarters in the dark. The app store is pretty decent for my needs- I didn’t see a true wallet app - but thats ok I can use my phone. As for GPS I haven’t tried it out in filed but it seems accurate. Unboxing was satisfying and well packaged with a upscale feel. I am overall very pleased with the value, appearance and functionality of this TRex2. I will update as time passes, and or issues occur. :)
