Amazfit T-Rex Pro Smart Watch 48mm, Rugged Military Certified, GPS, 18-Day Battery, Heart Rate & Sleep Monitoring, 10 ATM Water-Resistant, 100+ Sports Modes, for Android iPhone (Black)

I've been using the Amazfit Active Edge Smart Watch for a bit now, and it's a pretty solid device. The 46mm size feels substantial and the rugged design definitely gives me confidence when I'm out on trails or at the gym. The Mint Green color is actually quite nice, a subtle pop of color.GPS tracking seems accurate enough for my runs and hikes, and the AI Health Coach is a neat addition – it does offer some helpful insights, though I'm still exploring all its capabilities. With over 130 sports modes, there's certainly no shortage of options, which is great for variety.The standout feature for me is easily the 16-day battery life. It's genuinely impressive; I hardly ever think about charging it, which is a huge convenience. It paired up without any fuss with both my Android phone and my partner's iPhone, so compatibility isn't an issue.My only minor gripe is that sometimes the screen can be a little dim in direct sunlight, but it's not a deal-breaker. Overall, if you're looking for a durable, long-lasting fitness watch that covers all the basics and more, the Active Edge is definitely worth considering.

First, why I purchased the T-Rex Pro has everything to do with the two digital watches I had before I purchased the T-Rex Pro. Bear with me. More details about the watch itself below that.HUAWEI GT 2EMy 1-year old HUAWEI GT 2E watch strap broke and fell into a trash dumpster, which I didn't notice until it was too late. The $130 Huawei digital watch needed $4 screen protectors which broke almost bi-week, and the watch face eventually scratched up once I stopped replacing the protectors. The lesson here for me was that I wanted something more durable, similar to the Garmin Fenix 3 I had for 5 years prior to this watch.GARMIN FENIX 3My $650 Garmin Fenix 3 had come with a Saphire un-scratchable watch face. I loved this watch, treated it like a beast until the battery died (which is un-replacable). The memory for my love of the Fenix 3, with the bulky feel, and durable, sporty look, brought me to the T-Rex Pro, which is far less expensive. I was able to purchase the T-Rex Pro with a discount on amazon for $154.T-REX PROI've had the T-Rex Pro for several weeks, notably while moving locally and put it through an initiation where I accidentally clanked it against several doorways while walking with jumbo boxes in hands and it came through without a mark, even in one case having white paint stuck to the bezel from a wall where I had to peel off the paint with a utensil from the watch bezel. But no scratches through the 5 day ordeal despite the bezel hitting various doors, etc. The raised bezel no doubt has protected this watch face where the Huwei had failed time and again. As far as I can tell the watch face should hold up well without screen protectors.In terms of features, I've seen several reviews incorrectly state that you can only run one app on the watch at a time. They say, for example, if you've started the timer then you can't use the stopwatch, etc. Not true. When you have an app working on the watch just LONG-PRESS the "BACK" button and it will bring you out of the current app and back to the watch face where you can go back into your app list to select another app to use and run while the other one is working. It is possible to use multiple apps at the same time.I mostly use the watch for notification for calls, emails, and texts. It does an adequate job for this. I don't need to respond to them but just see what I need to get to while I'm out and about. The pop up notifications to alert you to a new text/email are a little too quick before disappearing for my tastes. When using the Notifications app to read an individual text/email, the messages are again on screen for only a few seconds before automatically kicking back out to the list of texts, so I need to go back and select/open the text again to get whatever part I missed. Also, a word in a text message will sometimes be broken up over two lines. It's not a huge deal in terms of functionality for but I also think it's something that should be fixed as it isn't professional look IMO. I can get past these small issues personally but you should know about them before purchasing this watch all the same.I love the look of the watch: the blue color suits me well and I like how the band feels more integrated with the overall look of the watch with the raised texture on the side of the band. In some online video reviews the blue watch color sometimes seemed a little greenish depending on the lighting but in personal it’s more of a matt blue grey which I do like and am pleased with. Please note, I've seen some people say there aren't replacement bands for this watch because they don't use the quick release mechanism on the band. You CAN purchase aftermarket bands for this watch but those bands require two small screw drivers (usually they come with the replacement band) and this was the very same process I used with my Fenix 3. The feel of the watch is good on the wrist and it's not too heavy. My fenix 3 had real heft to it which I kind of liked and wouldn't mind if the T-Rex Pro was even heavier. I imagine though most people would prefer the lighter feel of this watch.I downloaded a watch face that reminded me of one I had on the Fenix 3. I used the "AmazFaces" app from the iPhone store for a much wider selection of faces to download. Make sure in the T-Rex Pro "Zepp" watch app to toggle the watch setting for "Discoverable" to "ON" to be able pair and download watch faces from the AmazFaces app.The battery is very good. I still won't use an Apple watch because I don't like taking off my watch at night to charge and I like the option of not charging the battery for more than a few days. For instance, I misplaced my charger while moving, so I simply turned off all of the notifications, monitoring and special features, etc and I went 8 days using only 25% of the battery. But, should I turn all monitoring/features on such as heart rate, notifications, watch face always on, etc, I can use well more than 10% in a day. I like being able to adjust and balance what I want to use on the watch and keep a happy medium to battery length.All in all, I feel I have everything I wanted with my Fenix 3 at a big discount (sacrificing a little bit of the glitz of having a silver bezel, and the sports app, etc) but still have the pleasant feeling of a rugged watch that will give me a long battery life, take a beating, and provide the features I want.

Short version - This is a good value for the cost. You ARE able to use it with an Iphone, but the functionality isn't as seamless as an Apple watch, which is to be expected. This is the Amazfit Edge, not the T-Rex version. it seems a lot of those reviews are in with this one.Long version - More thorough thoughts coming from someone who thinks a smart watch is a "nice to have" thing and can't justify hundreds of dollars for a watch. I've had maybe 3 Timex Ironman watches over 30+ years, only replacing when it made sense such as a band breaking and it only costing about $15 more for a new watch over the cost of a new band. Or the water resistance failing after having to open it up and replace a battery. I once received a free apple watch that I used for a couple of years before it was damaged and died. So the comments below have some comparisons to that experience.Battery life - This is good. I have used this for a week and I charged it up to 100% and wanted to see how far it would go with the basic settings. From Friday afternoon, til Wednesday morning, it was at 15% charge left. This is with default settings, most features are on, and I'd used it a few times for walks using the GPS feature which I'm sure uses a little more battery. Compared to the apple watch, this is much better. I could get maybe 2 days out of that, but usually let it charge at night.Steps - This has been inconsistent. The device itself doesn't pair directly with the apple healthkit. It's the accompanying app, Zepp, that pushes information to healthkit. Some days the steps are the same, and then other days the health app will show thousands more steps. It's almost like it adds steps read from the watch to steps read from the phone itself. I've not yet tried to see if I can stop it from detecting steps from just the phone. If you are using just the Zepp app, this shouldn't be an issue. For my use case, I am using it to track steps/activities for an HSA incentive program. The app for that only gathers information from healthkit, so the information needs to come from there. It also does not sync with the activity "rings" for IOS. You can see your workouts in the activity app, but that's it. It captures calories burned, but not stand and activity in that app.Zepp app - It's an average app so far. As far as navigating it, I've used worse and I've used better. It's somewhere in between. For activity information such as steps, workouts, etc. it can only push information to the health app. They don't actually sync, and even then it seems to add to the information that's there, not combine it. I don't know if this is something the developer can resolve or if it's simply a matter of Apple not playing well with third party apps.Notifications (text and others) - These do work, but it's only notifications. For messages in messaging apps, like text or whatsapp, you can only see the notification. You can't respond to it. With an apple watch you can respond with default responses or voice dictation. It seems this watch has no mic at all. That said, they didn't work right away. Even with all of the settings enabled, alerts weren't coming through. After some trial and error I found that you have to have "notification center" notifications enabled in the app of choice for it to work. For example, for my text/imessage I had banner, lock screen, sound, and badges all enabled and it still wouldn't work. Once I enabled the "notification center" option, it started working. Maybe this is something the developers can look into.GPS - Works really well. From what I can tell, it's fairly accurate. So much so that when I go on a walk in my neighborhood it's accurate enough to show that I have walked on different sides of the road on the sidewalk. I'd say it's accurate down to maybe 2-3 feet.Sleep information - I've never used this on a different device, but it seems to work pretty well. Seems my sleep is better than I thought it would be.Watch face - one personal reason I didn't want another apple watch, I don't like the square face. It's nit picking, but it is what it is. That said, the look of this one is good. There are hundreds of options to change the appearance, however maybe 75% of them you have to pay for them. Most are in the $2-4 range. Another thing I liked better on the apple watch is the ability to customize what information you have. Most faces for this have steps, heart rate, stand, and battery life. Some have weather. But you can't set them to show what info you want, it's whatever you get with the particular watch face.Final thoughts - So far, charging from the 15% to 90% has taken about 35 minutes. Looks like a full charge should happen in less than an hour. I was concerned about functionality with the IOS operating system and some of those concerns were valid. My primary use case is as a pedometer and it does that with some extra functions, but it's not as seamless as I would prefer. I only paid $75 for it, which is about $30 more than what I would have paid for an Ironman replacement (it was about time), so I gave it a shot. It's a far cry from the $200+ starting price for an apple watch which I can't justify for a fancy pedometer.Hope this helps for iPhone users. I was hesitant because I hadn't seen any reviews specific to how well it may or may not work with an iPhone.
