Large and clear screen, very good and immediately understandable operating system. However, what impressed me is its battery life. I haven't charged it for 5 days while everything is running at full capacity, with 3 two-hour workouts, and its battery is at 86 percent. I think it's worth its money.
After 1 week of use and in CrossFit and swimming workouts. Very good battery. Large and clear screen.
Usually makes mistakes in heart rate and steps measurements.
It takes too long to transfer data to the app.
Very inconvenient strap for putting on and taking off.
The worst part is the round gear on the side. It gets pressed with any movement that bends the wrist and disrupts the workout recording. It ruins the entire workout measurement, and if your hand is bent for a long time, it gets pressed and restarts.
Honestly, I don't know why they put something that protrudes so much in such a place. It could just be a button, like in the previous model, and not cause problems for someone who simply bends their wrist.
It's simply useless in my workouts. I use the old xiaomi band 7
The Redmi is the definition of value for money. No problem so far, the measurements are ok, I have no complaints, the screen is quite bright even under the sun and with nice colors. I definitely won't try to put it in the sea, not because of the comments I read but I don't expect a relatively cheap smartwatch to withstand in seawater.
2 watches (Greek brand) came into my hands, and both were defective. The first one had a faulty microphone (during calls, the person I was talking to couldn't hear anything), and the second one made completely wrong measurements. The second time, I asked for a refund because I didn't have the patience to try my luck with a third watch and ended up getting a watch from another company. It's a shame, because from what I managed to see, I liked it quite a bit (excluding the defects obviously)!!
This is the second watch, I returned the first one because no matter how much you increase the volume on the speaker, it would reset to the factory setting on the next call.... Ummmm, the same thing happens with the one they sent me.... I'm not dealing with it anymore....
Excellent watch, many functions, easy to use, loved it, BUT it is not waterproof, yesterday at the sea it let me down, I didn't go to a great depth to say that I was at fault, so it is NOT waterproof. I am sorry because for the money it was a serious tool.
Very beautiful watch. Large screen, readable even under the sun. The connection with the iPhone was made directly. The only problem, which is also annoying, is that when you receive a call, the contact's name does not appear. It appears as "unknown caller" and below it shows the phone number. I tried various things, like resetting and changing the permissions of the contacts, but it didn't work. It's a compatibility issue with the iPhone. It works fine on Android phones.
There is no better option for collaboration with iPhone other than the Apple Watch with an obvious battery advantage (12 days with everything open and always on display instead of one day of the Apple Watch)
Very good. Of course, I bought a screen protector. No problem in the water. Long battery life. The measurements are decent. Excellent connection with the phone (Redmi 9 Pro). I highly recommend it.
It is much better than the watch 3, very clear screen and you can see better during the day, I hope the battery is strong as some others mention here in the comments... for now it seems to hold up well. For its money, it is a very good choice.
After 1.5 months it suddenly started rebooting continuously on its own, until it shut down and then displayed what I have in the photo. After that the watch is dead.
The device went to infoquest and I will have news soon for those who want to buy it.
Value for money, elegant and beautiful, battery lasts 15+ days, I believe that with 73 euros everyone will be happy. Plenty of measurements for various skin types. One drawback I have to mention is that it is not suitable for the sea. From me, 4 stars!!!
Nice appearance, fits well in the hand, honest for its price! In the first photo, I have put a transparent protective case on the watch so that I do not worry about scratches.
I bought it on Thursday, 30/5 from Public and wore it on Sunday, 2/6 for the first time where I checked it out for 10 minutes and then I jumped into the pool, resulting in the watch breaking the Touch Screen and staying permanently on. I wanted to know why they say it is waterproof
In the very positive aspects of this watch, it shows a very elegant and premium construction, has an amazing battery that lasts 7 days even if you have everything open and the screen constantly on, it has a good purchase price and a very bright screen.
On the negative side, I would have liked it to have NFC payments, but you can see that in much more expensive watches. I would have liked it to have a calculator.
The heart rate measurements when you wear it during exercise are not accurate, it shows something like 190 beats per minute which does not correspond to reality.
These inaccuracies only occur during exercise, if you wear it at another time to measure heart rate, it will show correctly.
It only has four tabs to add shortcuts, which is not a lot and this is a big drawback.
There is a moderate variety of watch faces that all look similar to each other, and there are no applications to add.
All of the above bring down the overall rating of the watch, there are other cheaper options that have more customization choices.
I won't comment on the straps because everyone can put whatever they want in the end, but it has an easy way to remove it and put on another one. Personally, I changed them with others from an international website.
In conclusion, I give it a good rating because it looks very beautiful on the wrist, but it's a shame because it could really be outstanding!
Very clear and bright screen with nice colors, battery that never runs out and I have most functions and notifications open, yet I charge it once every 2 weeks and I have a 20% remaining. It definitely easily lasts another 3-4 days with the 20%, I just don't let it go lower! Definitely worth its money. Connection with Iphone 14 is immediate and without disconnection issues.
I bought it for measuring heart rate, after seeing several reviews. Completely useless. Only accurate when you are sitting still. Just moving your hand a little, it goes up to 120-130
. Super screen. In dark environments, the automatic lighting should be a little more intense but it's ok as it is.
. Very good battery. Huge autonomy.
. Waterproof.
. Beautiful faces and customization.
. Satisfactory call control and notifications.
. Speaker, microphone work fine.
. The strap must be put on carefully, otherwise it may fall off your hand. First, you must attach the protrusion to the hole you want.
. GPS is very good.
. Counts steps and distance accurately with a small deviation which is fully acceptable.
. Great accuracy in heart rate monitoring (without exercise).
. NFC is not available in this version, but it is something that may be added in a future upgrade since it is possible.
Let's move on to the negatives now.
. Oxygen levels are low, around 90 in most measurements, on different hands, in every possible way. Therefore, oxygen monitoring during sleep is invalid as oxygen does decrease slightly and you don't know what the reality is in the end.
. During exercise, as soon as the hand warms up after about 10 minutes, it shows random heart rates. I had 152 and it was showing around 90s easily. Even during walking, it showed inaccurately after a while. On the other hand, I had the old one that showed values close to reality.
. Stress measurement is simply there so it's not missing from the features. The measurements are irrelevant.
And somewhere there, the return was made because the measurements were something I wanted and had taken for granted in previous watches without being more expensive (band, poco, and huawei and a Chinese one that measured decently).
Also, pay attention to where you will buy it from, if it is from a Greek dealership or if it comes directly from China. In the second case, in case of damage, repair times are around 40 days with the excuse that it was sent abroad. Don't skimp on the 5 euros. Get one from the Greek dealership.
The rating it receives is completely subjective and depends on the functions each person needs because everything the watch promises cannot be found in this version sold today. At least, this was my experience after 2 watches.
A pretty good watch especially for its price! Very good value with nice design and overall a great choice for most people!

Very good for its price, large clear screen even under the sun, I would like the speaker to be a bit louder when talking on calls through it but it's okay. Measurements are relatively accurate with a small deviation, the battery is incredible.
For its money, it's perfect. Great amoled screen, very good clarity, vibrant colors, measurements quite reliable as long as you follow some rules. The only thing that bothered me is the fact that when both bluetooth and the watch are connected and you start making a call, the bluetooth disconnects and you have to speak from the phone. While when you are called, it works normally and you answer via bluetooth. So, in order to make a call via bluetooth, I have to disable the watch every time!!! I think this is the only negative and it has already been mentioned by another user. I don't know if this specific issue can be resolved, but otherwise the watch is great!
So I start with the initial price. It doesn't have a full keyboard and numeric keypad. It doesn't have NFC! What exactly should I do if I want it for daily use?
Extremely honest for its purchase price. Without spending much, you gain an exceptional tool. Definition of value for money. I have had it for about a month and I am very satisfied with everything.
Very good screen in colors and clarity but it has two serious problems. First of all, it is big and often the crown button is pressed by mistake on the top of my hand, causing the system menu to appear. In one case it had to be pressed several times with a strange combination and brought up some recovery function in Chinese. I had to use google lens to understand how to get out of it. Secondly, the screen scratches very easily. Mine has a deep scratch that you can feel with your nail. I'm not even sure how it happened, but I think a screen protector is mandatory for this model. Otherwise it's ok.
I got it mainly because of the good reviews for the battery. Today is the 14th day and it has 19% battery. With everything open and talking several times from the watch. In my measurements, it seems a bit unreliable, especially the oxygen measurement, although personally I am not interested. Easy to wear, lightweight, does its job wonderfully for the money you give. Good purchase.
