Good quality and good flow

The product is at first good, the paddles are strong. The powered air flow is very correct for the size of the craft. The fan emits very little noise, thus not disturbing continuously. I take off a star because the flexible shaft is not great: it does not take great in certain positions (you have to try several times) and it is impossible for the twisted so as to have the USB plug into the other direction and the fan oriented correctly, annoying when the plug is in the wrong direction. It is not possible to stop without disconnecting it. It's still a good price / quality ratio. Note that it is not dangerous to touch the blades in motion, they are not sharp.
