Made me a believer
I've been interested in a smart watch but didn't want to pay the price of a big name brand. Turns out this was a great fit for me. I used it about half the day for 5 days and it's still 52% charged so the battery life is decent. The watch band is nice and flexible but I do take it off when I'm at the computer for long periods of time so I might try to purchase the metal band like my traditional watch. It did take me a while to setup, likely since this is my first smart watch. Signing up for an account gave me some odd error so I choose to just skip that which I prefer anyways. I was able to easily pair the watch to my smart phone. Then selected to get notifications from SMS, Phone calls, and specific apps. I found I didn't like many notifications so limited those. It vibrates with notifications and the bluetooth functions worked great for picking up and making calls. The health data works but doesn't appear to sync with my samsung health data so both track my steps. I did not wear it to sleep to test sleep tracking. I never could get the voice assistant to work with google assistant, on my samsung phone it keep pulling up bixby. But the alarms work, music controls work, stopwatch, calculator, and remote shutter were all helpful. Flashlight feature was interesting. My favorite was the ability to find my phone from the watch and visa versa to find my watch from the phone. I did try a few custom watch faces which was great since it's a lot of data on one screen and the always on feature was pretty cool to keep the time while charging. The only major issue I had was the weather data often gets polled from other cities with similar names but that software can be improved. The build quality is great. This is the tougher build version so I did wear it while working in the yard. Bumped into a few things but no obvious scratches on the screen or metal surround. It does measure 14mm deep, 42mm wide (not including buttons), and 49mm long (52mm including watch band clips). Seemed to have no trouble with water although I did not try swimming. Overall I'm happy, glad to be more technology connected at a price I still enjoy.

Absolutely hands down the best watch I've ever owned!!!
When I first opened the package, I couldn't help but notice the incredibly sleek looking design. It looks super fancy and the size of the screen is perfect, it's big enough to see all the features and numbers while at the same time it's not bulky to the point where the watch might feel heavy. I've only charged it once since I received it and I've been using it for about a week now and the battery is still 99% which is amazing especially for when I'm out in the country or camping for extended periods of time where electricity might be limited, the long-lasting battery life could come in handy for sure. Also, there's so many features that are super cool like I can literally customize everything exactly the way I want it. It's also waterproof, I have taken a shower with it everyday since I bought it and no issues with that. I accidentally dropped it at least a couple of times and there wasn't any damage, absolutely a beast! It looks and feels durable and the quality is definitely top notch. It's only been a week and I love it. I didn't find any issues with it, definitely worth every penny, and I would buy it again without a doubt!

Not reliable
Watch worked perfectly for 2 charges then the heart rate monitor went haywire. Was not accurate and caused me to return it. Really nice construction, and great look. I was disappointed it stopped working reliably.

After seven months of use
I am updating my review based on excellent customer service from Kospet. After posting my original review regarding the battery overheating and the watch no longer charging, the company reached out to me and sent me a new watch. I appreciate buying from a company that stands behind their product. The new watch has been working very well. It is a good smart watch, especially for the price. If you buy this watch, you might as well add the price of a new band because the band is cheap and rips at the pin that connects it to the watch. Other than the band, the watch is rugged. I use it while working on cars and have not scratched it. Battery life is good. I easily get two weeks between charges. The connectivity is good and the microphone works well. I like having the flashlight. Software updates and firmware updates have improved as everything is working as it should. Blood oxygen and pulse work well. Blood pressure is consistent. Sleep tracking is pretty good as well. I also like the fact that there are numerous watch faces available and I found one that displays the information I want to see on the watch and maximizes the size of the font.

A truly superior watch!
I recently returned 2 other smart watches within the last 2-3 weeks because the watch didn't have the option of displaying weather temperature in fareinheight, they were on Celsius only, this is of no use to me, and because of the poor quality of the faces designs, and the construction of the watch. This watch leaves the competition in the dust!! This is a well made robust watch, that has some heft to it, but not too much as to make it uncomfortable to wear. The displaying is crystal clear& sharp. Some reviews complained that the app for the watch, is not so good, personally I found this NOT to be true! The app is simple & easy to use, I had my watch completely setup & running perfectly just by following the steps in the app. I will mostly definitely be keeping this watch!! It's simple & straight forward to use, the display is crystal clear, easy to read. This is the only watch I have seen that gives you extended weather forecasts for the entire week!! No one else (to my knowledge) has this feature. If you are looking for a reasonably priced watch, that is extremely well made, crystal clear display, that gives you information that other watches do not, then this is the watch for you!! I'm sure you will NOT be disappointed! Enjoy your watch!!

From 2 stars to 5 stars
UPDATE: Customer service is second to none! After speaking with them, they are EXTREMELY helpful and put the customer first. You won’t have buyers remorse if you purchase one, but if you have issues, reach out to KOSPET, they really want to take care of any issues you have with the watch I didn’t take any pics because the watch looks EXACTLY like it does in their ads. Just under 2 weeks with it and it looks brand new out of the box. Pros: Great battery. 7 days and I’m at 47% battery life, very impressive compared to my Apple Watch. Love the watch face options, I have 0 complaints on the options. The watch materials are SOLID! Very durable. Easy to use watch and the app is user friendly. Find my watch works great. Cons: Doesn’t track steps properly. I have not taken the watch off in 7 days, and there three days where none of my steps were tracked. Heart rate doesn’t work very well, it just won’t read a heart rate. Disconnects from the app pretty often, it’s a little frustration but could get over that if everything else worked better. Find my phone is more of a joke than anything else. The phone does not alert, and the screen reads “IPhone found”. When I click Find my phone, the watch vibrates and makes sound and the screen shows “IPhone found”. Find my watch works great, but not finding your phone. The rubber watch band feels cheap, you’ll want to get a different one if you order one. KOSPET has something’s to work on for sure. I could probably get over most of the cons if the find my watch function worked. When I’m alone, I have a habit of setting my phone down and forgetting where I put it, and this was one of the major pros to the Apple Watch. I will be sending this watch back and look for something that works better. The watch looks great, it is durable, but the pros do not outweigh the cons for me.

Won't stay connected/ battery life shorter than advertised
This was the first smart watch, or any watch in 30+ years I have purchased. I got it because though I am in relatively good health, I am no spring chicken anymore. I bought this as a 60th b-day present to myself. I knew I did not want to go super cheap so I chose this one after doing some research, expensive is not always better, and it seemed reasonably priced as compared to most. So here is the good and bad. Positives: 1) Reasonably priced 2) Pretty tough and durable. The reason I have not worn a watch for over 30 years was I tended to destroy them. 3) Easy to charge The Negatives: 1) The battery life is not what it was advertised as. I get about 3 weeks out of a charge. Advertised at 60 days 2) It has trouble maintaining a connection and synch to my phone. I use a galaxy 21 plus. I have to restart the watch and sometimes my phone to get it to reconnect via Bluetooth. 3) Once reconnected, It has difficulty synching and can take several minutes once reconnected. 4) Not a fan of the band have to wear it kind of loose otherwise it pinches and is a little uncomfortable to wear. I find myself messing with it to much. That might be on me because I have not worn a watch in so long. 5) I spend quite a bit of time traveling and could not find just a charger for the watch, as it requires a specific one by the manufacturer. To take on the road and leave the other at home. That is why I needed a long battery life. When it gets down to it would I recommend this watch? Not sure. I purchased it in April 2024 and am still undecided as this was my first one, and I bought it mainly for the health monitoring features. I do not use most of the other features. But the features I do use seem to be good and relatively accurate. It has now been almost a year since I purchased this watch. So, I figured I would submit an update. I like the watch, but it fails to deliver on the 60+ days on a charge. At best I get about 3 weeks before I have to recharge it, good thing it charges quickly overnight. Second downside is the band it comes with is not very good and I am now looking for a metal replacement band. Beyond that I recommend the watch good product for reasonable price.

Durable, Waterproof, and Feature-Packed Smartwatch with Room for Improvement
I originally bought another similar smartwatch for my son, who was impressed by its functionality, and eventually decided to get one for myself as well. After two weeks of use, I can say this watch delivers on many fronts, especially in terms of durability and battery life. My overall rating has gone from a solid four stars to five! What I love most is its durability. After two weeks, the battery is still at 53%, which is outstanding compared to my previous watches that required charging weekly. This alone makes it a clear winner for me, offering a hassle-free experience without the constant need to recharge. As for water resistance, this smartwatch performs much better than my last one, which would often malfunction after contact with water, requiring a reset. With this new watch, I no longer need to remove it when taking a shower or during activities involving water, which is a big relief. In terms of functionality, I appreciate that it does the basics well—time and date visibility are clear, and the display activates when I raise my wrist. However, if you're looking for advanced, flawless integration with an Android phone, it may not compare to high-end Google or Samsung watches, or Apple watches, which tend to be better optimized for seamless functionality. For the price, it meets my needs just fine, but it might not be perfect for those expecting high-end smart features. My only gripe is the strap material. Initially, it felt like cheap plastic, which was disappointing. However, after using it, I found it more comfortable than I first thought. While I initially wanted to dock points for the feel of the strap, the watch's other features have won me over and helped balance out my overall impression. If you're looking for a durable, waterproof smartwatch with excellent battery life, this is a strong choice. Just be aware of its limitations when it comes to high-end functionality and materials.
