Review on Mackertop External Hard Drive Enclosure 3.5 Inches | USB 3.0 to SATA | Support for 3.5 & 2.5 inch HDD | 24 Months Warranty by Lynn Cole

The product arrived quickly and matched the written description ("vents" in product photo were cosmetic and not actually vents). The body looks solid enough. There is no side-to-side play or significant edge-to-edge play in the case, but there is a gap of about 1/4 inch between the hard drive and the top cover when the case is held on its side or when it is flipped over When moved to a new location, the drive may move and stress the SATA connection. As such, you'll probably want the case to stay flat and supported during use, unless you want to stick a small 1/4" washer under the top cover on the end opposite the SATA connector to reduce play . There are actually only a few tiny vents, and the case is made of plastic, which doesn't conduct heat well. After 2 hours, my hard drive was running at 44 degrees Celsius with a room temperature of just over 20 degrees. When I opened the cover 1/2 inch, the hard drive's temperature dropped to 42 degrees. If you live in a hot climate or want to keep your drive cooler you can remove the top cover and/or add a laptop fan while the external drive is in use. I have a couple of factory desktop drives and a couple of hard drives in Plastic or aluminum cases that get hot even without a fan, so this seems to be a common problem that the user just needs to be aware of.
