The worst purchase I have made. I bought two for the kids where: the touch works whenever it wants (and sometimes not at all), the measurements are terrible (you move your hand and the steps go up). The only thing worth it is its battery and that it looks presentable. Money wasted.....

Very good watch. And as for the battery life. For those who are looking for a simple watch (but it must be constantly connected to the mobile otherwise it loses time). Anyway, it is very good.

Quality strap. Durable and fits very well on the hand. Its battery lasts several days in a state where it needs to be charged once a week. Its measurements are average. Sometimes they have great accuracy and other times exactly the opposite. Its screen in sunlight simply feels like it doesn't exist, to the point where you think it's turned off

If you are looking for an affordable watch with a long-lasting battery that is comfortable for sports activities and relatively nice and discreet, it can be useful. However, its accuracy is minimal and I have tried to adjust it with different tightness on my wrist, but the measured deviation can reach up to 5 kilometers, sometimes 4000-5000 steps (as I count my exercise simultaneously with my mobile phone). Therefore, it has an accuracy of about 85%. It seems to record slow steps of everyday life... and fast running on the treadmill... anything in between leaves it unaffected!! Also, the screen is not visible at all in sunlight. Additionally, I have not found a function for cycling as mentioned!

Away on the third day the service of cubot Greece (Info Quest) did not open nor does it answer the phone. 50 minutes is not exactly a short time on the phone. Stay away.

The specific product was purchased for 10€.

The positives.
Readable screen indoors. Can't see anything in the sun.
Very good quality strap that fits nicely on the wrist.
The pedometer is quite good and relatively accurate, almost in line with Google Fit.
The battery. Up to three charges per month!
SMS notifications. Works properly.
Strong vibration but always vibrates four times.
Very easy connection with the mobile phone. Doesn't lose connection.
Sleep measurements are considered quite reliable.

The negatives. (with Nexus 5x mobile and Android 7)
Distance measurement is inconsistent.
Notifications for calls and other apps. Nonexistent. (This is likely due to the Android version).
Bluetooth range.

Overall, for the money I spent, it is very good.

It is good, especially for its price, it just has some minor issues. It loses connection at a very short distance from the phone and it is slightly inaccurate in measurements. On the other hand, the battery lasts a long time, it is convenient, the application works fine, and it has a good quality-price ratio. It is a good choice if you want something cheap and don't have many demands.

Very good quality in hand, screen brightness is a bit low but okay.
!! However, be careful, if you bought it for call and SMS notifications, there is a compatibility issue with devices running Android 7 (nougat), resulting in notifications not working. It works fine on Android 6, which was tested.
