What do users say? AI-generated summary

Users mainly appreciate the good value for money and battery life, while many find the watch well made and stylish. They also mention its calling capability and sports features, which make it useful for everyday use. However, several users question the accuracy of its measurements, especially the “medical” ones, and report Bluetooth connectivity issues and, in isolated cases, durability problems.

Excellent for its price. Compared to the Huawei Watch D which costs 449 euros new, it is very decent. Additionally, unlike the Huawei, it has full call functionality, which the Huawei did not have. The only downside is that it does not have an electrocardiogram. Accurate in other measurements. Lighter than I expected. I don't feel it on my wrist.

Unfortunately, it is like one of the cheapest Chinese smartwatches. No one should buy it. What they advertise as an advantage, the blood pressure measurement, is fake. It is completely useless.

I went in to see my review and realized that it does not mention that it is a certified purchase through Skroutz, even though my purchase was made through Skroutz. I think something is going on here.

  • I bought the Kepler smartwatch in the summer and have been using it every day since. Overall, I’m satisfied with my purchase. The battery life is very good, as it only needs charging about every 3–4 days. Its measurements aren’t completely accurate, but the deviations are small and they meet my needs for everyday use.

    Its main drawback is the Bluetooth connection to the phone, as it quite often needs to be reset to work properly.

    Overall, it’s a worthwhile smartwatch for everyday use, with good battery life and good value for money, though there is room for improvement, mainly in connectivity.

    For its price, perhaps the best choice. Very high quality and you can talk and answer calls. You can track whatever you want and the sports activities are very good.

    Today I just wore it, so I haven't had time to form an opinion, but the pressure it shows is definitely wrong, and quite a bit higher than what I get from a hospital machine.

    I bought it from the store and I was very satisfied. Its battery lasts ONE WEEK!!! Its performance is very good for its price and it is very stylish. The same model in Germany costs 120 euros. Anyway, even in the reviews I see that a couple of the negative ones are unverified purchases. Luckily, I always look only at the verified ones.

    The Kepler S25 is a big disappointment. Its battery lasts very little, the watch is bulky and heavy on the wrist, while its "medical" statistics are completely unreliable with measurements that change randomly or are not even recorded correctly. It is presented as a medical device, but in reality, it resembles an old, simplistic Fitbit. For 30 euros it might be acceptable as a simple gadget-watch, but its advertising is misleading and creates false expectations. I do not recommend it, especially to those considering it for medical use.
