Title: I am using two of these under DVR's, another under home theater receiver.
Review: As the box states, use with A/V equipment too. I had an old combo home theater receiver/dvd that I loved but it eventually quit due to overheating. So I just put one of these coolers under the new receiver (can't find a receiver/dvd combo anymore). Also have two directv dvr's and one runs hot so I put an Antec usb cooler under each. When I power down the dvr, the cooler still runs so after reading about the fragile cable and connections in previous posts, I will let the Antec run 24/7 instead of trying to keep unplugging. I may consider using a dedicated 110v/usb adapter like for my HTC smartphone in the future that I can unplug from the wall. I cannot vouch for the longevity of these USB coolers since I just purchased them.
Is this product review negative?
