    works as expected. Strength training tracking still as a lot of room to improve. it doesn’t track all movement nor detect all exercise as expected. Overall great battery life and great design!

    Bough this for cape wrath trail. Wanted long battery ( over 20 days) , GPS, route capability, and serious toughness and a hell of a lot more. It performed superbly. Great price . Was off grid for a week so this needed to be good.

    Taking this Amazfit watch out of its packaging you can immediately see and feel that everything points to this being a quality product. The watch is made of stainless steel and the strap is rubber which sits comfortably on my wrist.The watch face is all digital and can be swapped for other designs through the required app. The app allows you to setup your phone and collects some personal data to monitor various pieces of health data.Navigation on the watch is done by either one of the four physical buttons on each “corner” or by swiping the watch face to access the shortcuts – what is populated and their order can be amended in the app.Although the watch is marketed towards the outdoor and adventurous type of person, showing mountain climbing etc, it is more than useful for everyday purposes. With the help of the app, you can monitor heart rate at any time, discover how well you sleep, number of steps you take etc etc.The Amazfit watch is not that much bigger than a normal analogue watch and has lots more to offer, and the app is a necessary to get full use out of it. Battery life is amazing as I’ve regularly been using it and it still lasts over a week before needing it to be charged up again.

    This is a very smart looking smart watch. The rubber strap is easy to adjust and makes it very comfortable and secure to wear. It is super sturdy- my partner works on a farm and needs something tough. Set up was simple- it matches with the Zepp app.All the instructions and information are on the app and are concise and clear. You can customise the face and access various extras but although some are free, some are add ons which have a cost.It has a fantastic battery, it lasts for a week at a time, and is the best I have seen on a smart watch.The measurements it gives for pulse, blood oxygen etc are very accurate. My partner is currently having to check blood oxygen and pulse daily, and the watch gives as accurate a reading as the professional pulse oximeter we have been given to monitor it.No blood pressure reading, although you can enter details manually and keep a note of it.The reminder to get up and move after a set time is a great incentive to keep active, and there are lots of goals you can set. The sleep monitor function is also very useful and detailed. It has all the usual stuff like weather, calls, music etc but it is all extremely high end, and of a superior quality . Probably the best watch I have seen.

    I recently upgraded from a WearOS smartwatch to the T-Rex Ultra and I’m really happy with it! The battery life is way better than expected, the amoled display is bright and responsive, and the tracking of activities is very reliable. It’s also easy to set up with Zepp companion app and use and the controls are very intuitive. I have used Amazfit Bip 3 Pro, then GTR2e, now I’m using Bip5 and recently the T-Rex Ultra and all these watches have one thing in common – they are very accurate when it comes to heart rate, spo2 and steps measurements. And T-rex Ultra is no exception, I tried the HR and Spo2 measurements against a pulse oximeter and the readings are the same, counted steps against manual tally counter and again, the accuracy was spot on! the for the 1000 steps made my T-Rex counted 1003 steps of various stride length, that’s impressive. The GPS is also good, don’t really have to wait long (around 3-5 seconds) until the watch locks on GPS signal prior to starting an exercise. I appreciate this.The battery life is amazing. I got wifi turned off, but the watch its connected via bluetooth with my android phone constantly and the battery lasts me 7 days. This is very good, considering I got always-on-display turned on and I’m using GPS tracking during walking exercise at least once a day.The only downside is the rubber strap. It’s comfortable enough and I understand that this is an adventurer’s watch so this rubber will withstand everything but I prefer more refined style, so I ordered leather strap. Other than that I can’t fault it. Would I recommend it? Of course, the watch looks and works great and hence I’m happy with it I’m leaving 5 stars review. Hope this helps.

    I’ve had lots of watches for tracking data and fitness but can honestly say this is the best I’ve had. Battery life is great and last me at least a week. I haven’t used some of the features such as music but hoping I can soon. The display is nice and clear and I like the watch face being big but not massive. The app you download is easy to understand and pairing was a breeze. Overall if you want an accurate watch that measures fitness, heart, sleep, distance, and looks good then you won’t go far wrong with this one.
