I ordered a 40 x40 x10 fan to replace the noisy one on a 15 year old stereo given to me by our son. I was sent the wrong one. THAT's OK! I'll be taking advantage of your nice return policy. The correct fan arrived today, maybe yesterday. I just finished installation and power-up. At first I couldn't hear it and thought, "Uh oh, I should have done a fast test". Looked in the back with a flashlight, it was spinning. That is one da_n quiet little fan. Now when I turn on my little stereo in my nanobrewery I'll think of two things: My son and you guys. Thank you so very much. Hey! Guess who I'm gonna call next time I need a fan?Mark Bentler
Exactly what I was looking for
Wonderful experience, got my order super fast and very excited to find a source for little fans with a USB plug, I've been looking forever for these and work perfect in my tropical vivariums I build.
