Design of Haylou LS02:

Haylou LS02 design did not come with much, as it is similar to the previous version LS01 in the form of a rectangle with a large screen to shows more details and graphics, the manufacturing quality is excellent, as it is made of high-quality materials such as metal and plastic to save the weight, it does not exceed 38g and with measuring 48mm * 36mm * 11.5mm. And this what makes it skinny and light on the Wrist and does not cause fatigue during prolonged wearing, Even while you sleep, you won’t have much trouble.

The strap is flexible and softly, made of silicone to avoid sweat and itching in the skin, and it comes in a size of 22 mm, which means that it is removable and you can change any color or shape you want because this smartwatch is available in black color only.


We move to the display, it comes with a 1.4 inch TFT color rectangular display with a resolution of 320 x 320 pixels with a full touch screen And covered with a layer of curved glass 2.5D. And it has three levels of brightness, compared with the first generation, she gives the picture clarity, color saturation, and contrast for a clearer screen under the sun, where you can see the information well.

In the-end, Haylou smartwatch has provided users with 5 different watch faces, and users can make a choice according to their preferences. Unfortunately, there is no way to install more and this is a drawback for most inexpensive smartwatches.
