  • Customer Service and durable item
Color: 1.M2 Black
I’ve been using the AMAZTIM Smart Watch for some time now and I’m very satisfied with its overall performance. The battery life is outstanding—lasting up to 60 days on a single charge—and the rugged, waterproof design makes it ideal for everyday wear and outdoor activities. The 1.85" HD display is bright and easy to read, and the Bluetooth call feature (answering/dialing) works seamlessly. The AI voice assistant is a nice bonus and integrates well with both Android and iOS devices. I did encounter a problem with the charger initially. However, I contacted customer service and was pleasantly surprised by how responsive and helpful they were. They resolved the issue quickly, and I received a replacement charger within 10 days. Overall, I’m very satisfied with this purchase and would recommend it to anyone looking for a reliable, feature-rich smartwatch backed by excellent customer support. ... show more

  • Great quality, useful features
Color: 1.M2 Black
Gave as a gift. Recipient is a plumber and has put the watch through a lot of abuse. He has mentioned several times over the past year how well it is holding up, and how great it works. He says the app can be a little confusing, but the watch itself is great and has so many useful features.

  • The Best of the Last Four Watches I have Tried
Color: 1.M2 Black
I've been looking for the perfect "smart watch" for about a year now, and I've sampled four different brands, two watches within one of those brands. This one makes the grade, and it's the one I'll be using for the foreseeable future. Apparently the name of the watch and model is "Tank M2" although as with other imports, if there is a real brand name, it's a mystery. The box just says "Smart Watch." I found "Tank M2" on the enclosed User Manual. Some of what I am about to say is based on other comments I've read here, and I will lead with the most important one for me. I actually purchased this watch because of the claim of long battery life, and so far it is living up to that promise. After 3 days of pretty hard use, the battery is still at 87%, which suggests it will last the two weeks promised. One reason my experience may be better than others is that I don't use Bluetooth, don't see any reason to use the watch as my phone, and also disabled the feature that turns the watch on if one raises their arm. I know from my experience with other watches that that feature burns a lot of battery, and I don't mind pressing the button when I want to see the time. Several people have commented on the available dial faces and I have to say that I agree that the overwhelming majority of these dials seem to be childish and useless. But all that matters in my opinion is that there are a few dials that serve the purpose, and as you can see in the photo, I'm perfectly happy with this one. Now for the nitty-gritty on features: the sleep tracker is superb, best one I've found. I can't comment on Blood Oxygen because I have no way to know whether that's accurate, I guess I hope it is because it's giving me a good result. Several people have complained about the Blood Pressure measurement, here I have to strongly disagree and say that this is the best watch for measuring BP I have found. I have a medical cuff, so I can compare results. Of course they are not identical--for that matter, I get different results on my cuff from the one my physician uses. The watch is within 10 points of the cuff on both systolic and diastolic. But that's all missing the point. No one should be relying on these sorts of devices for Blood Pressure other than one important thing: if the watch reports that you are having high or low BP, that's an indication you should get a check up. That's what matters. Of course these watches were designed to count steps, and the step counter on this watch seems to be extremely accurate. There's very little lag time between starting to walk and the watch starting to count those steps. This brings me to the one issue I have had, and the reason I'm withholding one star from my review. For some reason, the watch uses a standard of 4000 steps to a mile. Not only is this wrong according to my other four watches, it's wrong by a course I've mapped out using my car's odometer. According to all four watches, a mile for me is between 2300 and 2500 steps, and according to the one-mile marked course, I need 2325 steps for that mile. I have contacted the company's technical service department, but so far all they've done is offer me an extra watch strap for my inconvenience. I'm happy to accept the strap, but I'd also like to have a more accurate distance measure. Wags like to recite "your mileage may vary", but here the problem seems to be that the mileage isn't varying--it's stuck on 4000! The watch does seem to be built like a tank, I have no worries about its durability and water safety. For now at least, this is the watch I'll be wearing every day, and compared with the other four watches I have tried, I'm willing to say it is also the best "bang for the buck." ... show more

  • So close to being the best.
Color: 1.M2 Black
The media could not be loaded. This is a really nice watch! It's got a lot of nice features. It fits well and is comfortable on my wrist. I didn't use the band that came with at all and switched immediately to a flexible bungee band. So I can't speak for the band comfort at all. It's got lots of different Fitness and sport trackers as well as movement recognition. It's got lots of different watch faces as well as allowing you to use your own images as a watch face. It plays music and can make and receive calls. It charges as quick and lasts as long as I need it to. Overall it's a really nice watch... And it's so close to being the best. The main issues I have I feel are relatively minor. First there seems to be quite a bit of redundancy. In other words I can access the same feature three or four different ways. I'm the kind of person that likes to have everything in one place and that's it. There isn't a lot of customization that you can do to move around feature icons. I do receive notifications... My issue with this is there is not a lot of distinction between different types of notifications. Messenger and SMS text have their own icons. But as for email, gmail, teams, and every other form of social media notification... They all look the same. Lastly, I can only receive SMS texts. But on my Android phone I use Google RCS chats. Which is a higher quality form of texting with added encryption security bonuses. This wash is not support that form of messaging. So I don't receive those notifications at all. And a smartwatch that doesn't does not distinguish or recognize smart notifications... Doesn't really feel like a smartwatch. I think with a couple more software updates and tweaks this can go from a really good smartwatch to the best smartwatch! When it does I will come back and give it a five-star review! ... show more
