What is the device capable of?

The capabilities of this gadget do not lag behind its visual appeal. The bracelet has everything you need to perform high-quality and regular diagnostics of the main indicators of the health of the human body:

  • An accelerometer is installed that calculates how many steps the owner of the device has overcome during the day. There are certain norms of daily walking activity, which are one of the main ones in maintaining a healthy lifestyle and maintaining good physical condition. At the same time, the accelerometer works in dynamics — the indicators of previous days are recorded, and the owner is able to view them in the form of a graph. So he can see when he managed to complete the daily norm in steps, and when it turned out to be lower;

Display and case

Included fitness bracelet GSMIN B3

Separately, we would like to say about the display. Its diagonal is 1.14 inches — we could easily read all the information displayed on it. It is quite bright and contrasting, the picture is clear. Everything is easy to read on it even if it is under direct sunlight. The products are well resistant to various kinds of physical influences, there are no traces left on it: no chips, no scratches, no cracks were noticed.

The case is metal, which is not so common in similar products. The metal is pleasant to the touch, does not stick to the skin even after a whole day of wearing on the hand. The strap is silicone, takes the shape of the wrist, while not pulling it. We did not notice any discomfort while wearing. It withstands both high and low temperatures well, without any consequences — cracks, fractures, deformations. The mass of the device is only 42 grams, so it is practically not felt on the hand. You get used to the bracelet very quickly, literally in a week its lack on the arm becomes very noticeable.

What gadgets are compatible?

The GSMIN B3 fitness bracelet is equipped with a built-in Bluetooth 4.0 module, which allows it to be synchronized with various devices based on iOS version 8.2 and higher and Android 4.4 and higher. By and large, this gadget is compatible with most modern smartphones and tablets, which adds to its versatility.

The battery is quite reliable — without recharging, the design is able to work for 5 days. This allows you to take it with you on long business trips, trips and vacations, even if it is not possible to recharge the device. The battery charges in just two hours.

Adds practicality and moisture protection, corresponding to the international class IP67. Due to this possibility, the bracelet can come into direct contact with water without losing its performance. We did not swim with him, but we washed our hands and got caught in the rain a couple of times. There were no problems with the device after that.

What's included with GSMIN B3

Our impressions of the device

We wore the gadget for a week. Generally speaking, it sits on the hand at first not too familiar. You get used to it in just 1-2 days. All indicators of the body are measured quite accurately. All indicators were checked quite trivially — they were measured first on a fitness bracelet, after which pressure and pulse were measured on a tonometer. The difference was only 5 points up, when compared with the pulse, the pressure also overestimates a little. The most important thing is that the bracelet sits tightly on the arm, if it does not fit snugly, erroneous measurements are possible.

This bracelet turned out to be very convenient when using the device as an addition to a mobile phone. He receives calls and SMS messages. When a call or SMS is received, the gadget emits an appropriate vibration, so we didn’t miss even important calls. The connection with the smartphone is not always stable, during the tests I lost connection with the smartphone several times (perhaps it was due to the local remoteness of the smartphone from the bracelet — they were in different rooms). The pedometer is accurate: we counted steps for half an hour, then compared it with the indicator on the bracelet — it matched one to one. They did not dare to test under water.
