Pros: -Functions flawlessly in multiple usage environments -Remote flip button makes input changes a breeze -LED indicators for PC input -Bundled cables are well designed and durable -Extremely reliable -Well priced If you are in need of a 4-port KVM, look no further. I've ordered many of these units for use at work and at home - never once have I had an issue. Simply put, this is the best KVM you'll find for under $50.

Cons: None

Pros: -(4) 2.5" HDDs in a single 5.25" drive bay -Uses only (1) SATA power connector -All 4 SATA connectors are located conveniently on the back of the unit -LED drive access lights actually work -Cooling fans included and actually move air (unlike most competitor models -Low cost

Cons: -HDD hot swap latches and trays are made of cheap plastic (be careful when removing and replacing drives) -Limited positioning of screws for mounting the unit in drive bay

Overall Review: I was able to use this HDD cage in a small form factor HP desktop, which has only 2 SATA power connectors and really no room for any additional hardware. The fact that the cage takes ONE single SATA power connector and uses it to power FOUR hard drives, plus another (2) cooling fans, all in a single 5.25" drive bay is awesome. Plus, the LED activity lights actually work and the bays are hot swappable. All of this for such a low cost. There is a bit of a gap between the top of the cage and the top of the case drive bay, but this may simply be the case, rather than the HDD cage.
