  • I have it for 5 years, it's a war dog, no frills.
    I also do dives up to 10 meters.
    It hasn't suffered the slightest damage, only the strap which was replaced with a bracelet

  • I bought it in 2019 just before the problems with the straps. Initially, like everyone else, I had an issue with the strap. It would come undone... didn't fit well... etc. I solved the problem with the metal bracelet that attaches with a magnet. Its battery life is good and overall it is reliable for basic functions. What bothers me is that every time I need to charge it, I have to completely remove it from the base or strap. Since only the device needs to be connected to the special charging case. Other than that, it's worth it for something simple and cheap.

    I have had it for almost 2 years and it hasn't had any issues. Only a few scratches have appeared on the screen. Also, it doesn't measure the distance and calories accurately. However, overall it is good.

    The watch is very good. I have had it for three years. My sister wore it in the sea and it didn't suffer any damage. It is very good except for the strap that constantly comes undone and breaks, but you can order another strap.

    Battery life is quite good, it lasts up to a week. The only negative is the build quality of the strap, which can be easily replaced.

    Nice design. Unfortunately, its measurements are not very reliable... it doesn't count steps correctly (it counts many more, just a little movement of the hand while sitting adds steps...) Nor does it accurately count heartbeats.

  • For its price (30 euros), it is excellent, it's just that sometimes the mobile notifications do not come to the watch and the steps are measured incorrectly.

    I give it 4 stars because... the watch is very nice, it has an app where you can put wallpapers and it's perfect!!! The only downside is that you have to be careful with seawater, because it's sensitive and water got inside and the screen got wet, but no problem because I had it since it first came out. Another good thing is that it has a good price development, meaning that when I first bought it, it was 50 euros and now it's 20 to 25 euros in the market.

  • The mi band 4 was the best purchase I made in a smartwatch, I just have two complaints. The first is that the strap, because it is made of silicone, will wear out with a lot of water. And the second is that its measurements are not so accurate. But overall, I was impressed with the screen, battery, and the watch in general.

    The best of all!!! No one swims 1000 meters, it shows 1500. It tells you that you burned 400 calories so you are ready to swim your laps without regrets! You wash the dishes, it tells you if you reached your daily step goal ????.
    Therefore, it is the best band to feel fit without actually being! Every Greek's dream!!
    On the other hand, it is super expensive for something very important...the time.
    For a kid to learn what movement means and to see the time, it is perfect. Until there

    I have it for two years, it is perfect! The strap broke a little, but okay, it's been two years, I will replace it and everything will be okay. It's worth 100% of its money

    Do not spend more money to get this strap. It broke in the first week. There are very nice high-quality straps that you can get which are like jewelry.

    The band was satisfactory in measuring heart rate as well as battery life, as it lasted up to a month with the features activated and had equally good brightness. Also, the measurements during running, which I mainly used it for, seemed quite accurate, with the distance, heart rate, and speed appearing to be correct. However, the sleep measurements were rarely accurate, either missing many hours of sleep or not recording them at all. The strap broke after about a year of wearing it, although I did wear it a few times in seawater, which may have played a role - straps from third-party companies did not last longer than two months. Overall, it did not keep me satisfied in terms of sleep, but I can't say the same for the other features at this price. Now that newer models have been released, it definitely isn't worth it.

    The accuracy in steps is not good, it counts steps inside the car.
    The connection with the mobile is easy, the battery life is very long, 24 days without charging.

    Very good band. I never part with it for the past two years that I have it. Its battery is strong and lasts for 30 days. I highly recommend it. Its disadvantage is the poor quality strap that broke and the charging method

    It is the second one I buy. The first one, the screen came off over time (as if the glue polymerized). Now, in this one, the rubber strap broke within two months. The strap is terrible. However, overall, it is worth it for its price.

    Very good, the only negative thing is that the alarm clock automatically sets itself to 7:00 and that the strap breaks very easily. I have already changed 2 straps.

    Excellent! The 15-day battery life is of particular importance. The screen is of such a size that there is no issue even without reading glasses.

    I have had the watch for 1 year. It is worth its money, but the only negative thing is that it counts more steps than the ones I take (it might be due to the mobile app, I don't know)

    Good evening! I have had the watch for two years and I would like to talk about it a bit....
    Firstly, these are its positive characteristics:
    Beautiful screen
    Large battery
    GREEK
    Nice and quality strap. Also, you can find many similar ones on the market.
    Several functions for a 20 euro watch
    Negatives:
    Large bezels
    Bad software (mi fit)
    Charger (you have to remove the band from the strap to charge it)
    Prefer the band 6 over this one. Or better yet, if you don't want a band, save money for a smart watch.

    After two years of daily use, the battery broke. For its price, it is a very good choice even if it breaks every 2 years.

    This review is about the colour: Pink

    It was good but it counted steps even when I was sitting in the car (!) and even when I took it out of my hand. Also, the strap doesn't tie, but it fastens to a hole, resulting in it not being secure and me losing it within a week. It slipped out of my hand, I fastened it again, and after a while, I realized I wasn't wearing it. It had come undone again and was lost. It is lightweight, which is positive because you don't realize you're wearing it, but on the other hand, it is negative because you don't realize you're not wearing it (when it slips off).

    It is a very good watch. It is waterproof, charges quickly in general, and can be easily adjusted from the mobile phone. I have had it for two years and it is still alive (compared to others). I don't know what I would do without it. When I don't wear it, I feel like a part of myself is missing! The only thing is to take care of it from scratches and charge it before the battery goes below 20%. It is a fantastic watch!

Δεν νομίζω πως χρειάζεται data/wifi το κινητό για να δουλέψουν οι ειδοποιήσεις στο Band μέσω bluetooth

Nina_Touki

Έχω το προϊόν από το 2020. Τελείωσε η μπαταρία και το έβαλα να φορτίσει, το έβγαλα πριν λίγες ώρες και δεν άνοιγε η οθόνη ενώ το είχα δίπλα μου και πρόσεχα ότι φόρτιζε κανονικά. Άνοιξα Bluetooth και η εφαρμογή το αναγνωρίζει κανονικά αλλά όταν πατάω να κάνει εύρεση δεν κάνει καθόλου δόνηση. Πως μπορώ να το φτιάξω;
