Rotatable USB Desk Fan

Third purchase, is an excellent product
Has 3 speeds
Is very firm
It took a week to arrive

Personal, in the photo I put the model K50 (white) and the model K52 (blue). I bought the two together and I'm still testing, but I noticed that from what you can see in the picture, the K50 has a more robust construction and the K52 tries to be more "delicate" in design. Good, The K50 and K52 seem to produce the same amount of wind, but the K50 seems to have the advantage of making a little less noise. Is nothing so noticeable, it seems more that there is an equal noise in the two and in the K52 there is something making a more acute noise, which in the K50 does not have. It may be that the K50 came better by luck, because in mass production there is variation in quality. It may be that the K52 has something different that is in the propa, which has a different engine, but I do not know about this technical issue. But, in the end, I would take the K50, in case I go and buy it again.
In addition, they really do a lot for the size, but they make more noise that I would like. Do not replace a large fan, losing in almost everything, but winning a lot in space.

Sent quickly, arrived quickly, the price is great. One of the best fans, crazy and powerful

Excellent mini fan, small but large power. I have already bought two of these

The fan blows very well even at 2nd speed. Recommend! In the photo there is consumption in amperes 1,2 and 3 speed
