Review: 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 Speaker I 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 such Insights 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 process The 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.
Review: 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!
