I've had this item installed (am using it to control 8 fans, 4 for intake, and 4 for exhaust in my entertainment cabinet) for about a month now and it is performing flawlessly! The time that it took to arrive @ my house from Hong Kong was VERY surprising, I expected it to take @ least 2 1/2 weeks like most other item that I have purchased wholesale, it took 6 business days... That's the norm for things from California to VA (my place of residency). Again kudos to suntekstore!

The motor controller produces almost NO heat whatsoever even with it turned to 1/4 power, any lower and the fans just make a whining noise from too little power to rotate (12 volt DC Brushless VAPO bearing) manufacture specs state the dBA is @ 44, with the controller it is approx 19 dBA. Almost unnoticeable during normal TV viewing, however with the nob cranked wide open on the controller.... BOY OH BOY do those fans move some air AND make a bit of noise! (a bit of noise is an understatement) I can hear the fans without a doubt.
Bonus is that it helps keep the room cooler ha ha.
Long story short, get this controller... You won't be disappointed

BTW, they sent me the one with the black control nob, I wished it would have come with the chrome control nob but I honestly didn't expect to receive the aesthetically pleasing one. Oh well

Product came much earlier than expected. I thought it wouldn't arrive for at least another 10 days. When I hooked it up, it worked flawlessly. Thank you for great service and a great product.
