The most important pro tip is its price, but the relation price/quality is not bad either. Very easy to configure, no need for a manual yet it comes with one. Ideal weight and it really looks cool in my wrist. The item's packaging is careful, it came in a paper box, unbelievable Everbuying would spend so much on packaging. Another merit of it is the duration of the light, when turned on it last less than one second to turns off itself, automatic power saving.
Happy with the overall quality, it is recommendable.
