It arrived with the switch broken and even though I could turn it on, it didn't work at all, only the light bulb would turn on

Very good for its job.. meaning keyboard cleaning, crumbs, ashes, etc. It is quite small so it can be easily stored on a desk. The light also helps. I have one for 6 years and it still works great. Those who thought they would get a car vacuum for 2 euros are mistaken.

Plus: it has a relatively long cable and if you plug it into a charger up to 2-3A, it works fine.. (the pc gives it .5-1A (: ) I plug it into one like that (MX-HC46) and it works perfectly (2+7eur!).

These do nothing because I have tried several. One or two suck the thicker ones only and the other four don't even make a dent... It doesn't have a button to open and close, and the attachments don't tighten. As for the brush, it's terrible because when you put it deep into the gaps of the keys and the bristles fold to collect from underneath, they get stuck and come out, and in the end, it will be bald... If the keys are more spaced out and not almost tightly packed, it kind of works.

I don't know if it was my defective one or if that's how the vacuum cleaner is, but the attachments of the nozzle do not fit well and I have to hold them with my hand. Also, it doesn't have an on/off button, you just plug it in and it starts. Finally, it doesn't pick up much dust between the keyboard, only on more open surfaces.
