Pros: Well built and nice looking, highly functional. I like the way round cable bends and moves at any axis.

Cons: The downside to round SATA cables, I discovered, is that at the connector they are a bit fat at the transition to the wire. This may require that I swithch to flat cables, should I need to add so many drives later that I need to use mobo connections that are "stacked" tightly together.

Overall Review: In tight situations where connectors are stacked tightly, go for flat cables.

Pros: Cheap. Maybe a good back-stock replacement to have on hand to use while you pick out and order a real fan. Better than no fan at all.

Cons: Installed 3 of these, one to replace a stock Corsair and 2 as additional airflow. One started rattling and buzzing in less than a month. Removed them all.

Overall Review: Don't use these in work you are doing on other people's machines, no matter how cheap the customer is. Maybe get the four pack intending to use 2 and keep the other two for replacements.

Pros: Well built and good looking, 3.0 speed.

Cons: None

Overall Review: In my most recent build I wanted to keep things minimal and clean. I opted for this as opposed to an over-priced junky card reader or bay device. I just keep it in a drawer whe I'm not using it. I only use on type of card (DLSR) so this is vastly less of a burden on my system as opposed to all the inactive drive letters and buggy drivers you get with drive bay mounted card readers. Think about it before you build.

Pros: Clean, solid, good-looking.

Cons: None.

Overall Review: Don't ever skimp on any internal wiring. Your machine cost hunderds, maybe thousands. Why ruin it trying to save a few dollars by buying garbage wiring?
