    Feature Packed and High Quality
    Have had this watch for a week and I absolutely love it! It was very easy to set up and linked flawlessly to my Runkeeper account. After several hikes and workouts, the gps is extremely accurate, the heartrate monitor provides valuable info, and there is so much other workout data available!Sleep tracking is making me more aware of how I rest!It is very durable and high quality. No problems seeing screen in full sunlight. I’m on the 10th day since I charged it fully and there is 48% battery left, which is awesome! I can’t believe the functionality of this, as there are so many things on the Zepp app that I haven’t even been able to fully grasp what all is possible with this watch.Highly recommended for the quality and amount of options and functions for the price!

    Durable and bright
    I switched from an Apple Watch to the TRex. The main reason I wanted to switch was battery life. The Apple Watch at best could get 24-30 hours, but general use 24hrs was my average.I looked at the Garmin Fenix 8 but I really just didn’t want to pay that price. I watched review after review and felt the TRex was the right fit for my needs.Concerns before I purchased:- messaging- calls- no SpeakerI have had the device now for about 45 days.Durability – this is a solid watch. I have been doing a full kitchen gut and remodel. I have warn this watch the whole time and it looks like me. No scratches or evidence of any damage.Battery Life – I think confidently 18 days is consist. The first few days I was messing with the settings and looking it over a lot so battery was only 10 days after charging to 90%. I think you could get even more if I turned off notifications and brightness down.Navigation and menus – the OS is really smooth. Very fast to respond. I like the mix of buttons and touch screen. Especially when you have gloves on and suchInsights and Health – I think it is far more accurate on steps than my Apple Watch. I wore both watch’s on the same wrist for a full day and I never realized how many non steps my Apple Watch was picking up. I was sitting and typing at my desk. The Apple Watch picked up a nearly 100 phantom steps. The TRex picks up stress pretty well. It notices when I am thinking about a topic that is stressing me, like “is my flooring going to arrive in time?” Or “we only have x hours to complete this before the contractors are here!” Lots of good health habit reminders and such. I am looking forward to getting more use out of them once this project is over.Price, quality, and worry – when you have an expensive watch you worry about damage. It’s not to say I don’t worry about this watch, but when it’s 1/3 or 1/5 of the price of the other watches you looked at, it’s nice to be able to just enjoy it. Lots of compliments on its appearance and screen brightness. A lot of watch for the processThe gaps:I do have moments I wish I could do a voice reply to a text or quick reply, but Apple doesn’t allow that.No speaker is a kind of a bummer and I typically don’t pair my headphones to my watch, but that would be nice to be phone free for a run or workout.Overall, I really like the watch. I thought I would miss the Apple Watch integrations, but I don’t. The TRex still has the camera remote and find my phone features. I don’t really notice anything yet that I miss from my Apple Watch that I would say is a “send it back!” Thing.Updates are fast and so far little tweaks will continue to improve it. I would by it again.

    Best sport watch for your buck
    For the money this seems to be the best value on the market. The app that goes with this watch is well done, and your sleep, heart rate and stress is monitored as you move through your day. I ride a bike every morning and it shows the route on GPS and reports the miles and the speed of the ride. This watch does more than I have the time to set it up, and the battery goes for about two weeks. Take a look at YouTube for more analysis than you can stand

    Love this watch! Better than Apple!
    Amazing display, super clear and unusable amount of apps, but I have one for anything that I wanna do simply amazing great strap flexible, comfortable or workouts even looks good with my suit. I’m super happy about this purchase. I’ve used the sleep tracker and the sleep quality and they both seem to be very accurate. I’ve also used the GPS and location also seem to be very accurate. Amazing quality for each price.

    Very Good Low Cost Option For Smartwatches
    First Im leaving 4 stars just cause I have only had the watch for 3 days. Having said that I really like the watch. It is easy to navigate, the weight is perfect barley notice it. Full disclosure, I only use the watch, weather, sleep, heart rate, blood ox, and step counter functions. I do not use it for work out stuff yet. I am a truck driver so im constantly on the road and get home late. Anyways if your looking for a review to help you decide, I would say get this watch. I have ocd when it comes to making purchases such as this. I have watched all the videos and reviews and this is definitely a solid choice for a smart watch that is budget friendly. It looks good and functions good. So far after three days the battery is at 69 percent. It is suppose to have I dont remember either 10 days or 14 days before you need to charge not sure it will make that, just depends on what you have turned on and what functions you got going. Side note this is my woman’s Amazon account so this opinion is from a dudes perspective. If your a fitness junkie always working out everything I have seen from the videos everyone says this is a great watch for workouts.

    I only had this watch briefly, but it is great to see a company pushing the technology and software that once only seemed available in watches 4-5 x the price.This watch is a great substitute to the Apple, Samsung and Garmin brands of the world, basically giving you the exact same tech and abilities, for a fraction of the cost.However, don’t expect all the bells and whistles of perfect phone integration, compatibility with thousands of apps nor the ability to phone home with this brand. These are the concessions you make by paying far less, for an equally capable, rugged, well polished watch, without a thousand dollar bright shiny name on it.It will still jump out of a plane skimming the stratosphere with you, while plunging into the deepest depths of the ocean with you, and tell you the time and possibly your heart rate while doing so. It just won’t make you feel guilty for overpaying for the privilege of having a great watch on while doing so.It runs apps beautifully, and gives you a nudge on the arm every time someone uploads a family portrait or lunchtime selfie, and will let you know when your boss is calling to find out where you are. It just won’t say that the call is brought to you courtesy of Apple, or Samsung, or Garmin. And that’s probably worth saving a few $$$s for.Highly capable, highly recommended watch.
