It's not something i would leave sitting plugged in; it's not exactly silent.

This thing will heat up a fair bit, but that's the trade off for the amount of power it can put out, i suppose.

It's a little bit on the heavy side for it's size, and definitely feels like it's not made of cheap plastic.

Quite noisy fan for such a small device.

In my case, i could fit this one into my 12v socket but the other one i couldn't fit at all.

Could be a little better if both usb ports could support their full rated load instead of sharing only 3.
