Positive:
- It seems to be a quality construction.
- The keyboard cable is quite long (about 1.5m).
- The mouse LEDs are bright and the colors alternate (I don't know if I can choose a specific color, intensity, or pattern).

Negative:
- The mouse cable length is short (about 1m).
- Lack of support. The website mentioned on the packaging does not exist (www.loophole.hk) and a Google search only returns Greek e-shops that sell it.
- There are no basic instructions for the "RGB" keyboard, which my son accidentally discovered that the LEDs turn on with the scroll lock key, but the colors are probably static (they do not alternate or are not programmable). At least I haven't figured out how, if this feature exists (if it does, someone please enlighten me so I'm not unfair in my evaluation).
- The keys are not illuminated (in a dark room, the letters are not visible as the lighting is underneath, at the base).
- The keyboard LEDs are relatively weak, unlike the mouse LEDs (see above).

On the other hand, with a purchase price of €12.50, maybe I shouldn't have high expectations... it's not like it's a RAZER!
