Review on 💨 Honbay 4PCS Mini USB-Powered Cooling Fan Gooseneck Air Blower for Desktop PC Laptop Notebook Tablet - Portable & Mobile by Robert Carter

These are very inexpensive fans; others so much for 1 fan and this set includes 4 fans. The old adage "you get what you pay for” applies here. I've used 3 out of 4 fans so far; 4 is still in the package. Fan #1 works great! Nice, quiet, powerful fan. I'm actually quite surprised (in a good way) by the amount of air they produce. Very powerful for such a small and simple device. 5 Stars. Fan #2 also works well but is a bit noisy. Like he's out of balance or something. However, based on my usage, the noise is not an issue. Hence 4 3/4 stars for it. Fan number 3 is a different story! It worked great on the first day of use. The next day it started making a lot of noise (similar to but worse than fan #2 noise). The noise got louder each day as I used it until around day 6 the fan blades and motor came loose from the case so I had to tie them together to use it. On the 7th day when I turned it on the entire motor flew out completely and pulled the wires out of the motor. (See pic.) Only 1 star for this one (I'd give it 0 stars if I could!) A rating from fan #4 will be added after it's been used.
