Small stature, big energy, more than just a little Willful s


Because I don’t like the feeling of wearing a bracelet or watch, I haven’t experienced wearing a watch or smart bracelet for a long time. I accidentally saw the introduction of the Willful brand Y2 smart bracelet on the Internet. I actually have blood pressure, blood oxygen detection, etc. Nearly 20 functions have subverted my understanding of the functions of smart bracelets a long time ago and aroused my curiosity.

I couldn't help but place an order and bought a standard version of the black Y2 (with a chest patch set + real-time blood pressure and heart rate monitoring), and actually experienced it.


This Y2 smart bracelet from Willful is packaged in a white carton, with only a golden “Willful” logo on the front of the box, no other decorations, and an extremely simple appearance.

The interior is filled with delicate soft foam, the wristband support and card position are firm, and the protection is in place, which can definitely effectively resist the violent sorting in transportation.

The watch also comes with two electrode adapter plugs and two electrode pads, which are used to monitor the ECG on the chest, and a simple manual. Didn’t see any chargers and charging cables, a bit strange, right?

The upper part of the front is equipped with a curved glass screen shield, and the lower part is a curved gray metal touch panel. There are two small holes, perhaps buzzer holes.

The host adopts direct plug-in USB charging, and the charging electrode is hidden inside one end of the plug. No wonder the charging cable is not seen when opening the box. The host has a battery logo on this side for easy identification when removing the strap. There are two ECG monitoring electrodes at both ends of the inside of the main unit, and five photoelectric monitoring windows for monitoring heart rate, blood oxygen and blood pressure in the middle.

The Y2 bracelet also comes with an ECG monitor adapter for measurement close to the heart, which can be connected to a professional heart rate belt by covering the plugs at both ends of the main unit, or it can be installed with electrode patches directly attached to the heart for measurement . Compared with wrist measurement, it is more accurate.


The Y2 bracelet has a moderate size, exquisite workmanship, and a more atmospheric look and feel, especially the black curved panel that adds a lot to the bracelet. The rounded appearance, without a trace of edges and corners, also prevents some bracelets from hanging clothes, especially sweaters, which affect the wearing and taking off.

Whether you are hiking outdoors, riding long distances, or exercising indoors on a spinning bike, you can wear the Y2 bracelet to monitor relevant body parameters and exercise data. However, under strong direct sunlight, it is quite difficult to see the numbers on the display screen, which requires a little shade.
