Pros: Trayless!! no screws required to add drives. Looks cool and allows me to fit 5 drive in 3 bays. I have 5 Seagate 1TB 7200.10 that remain cool while in operation.

Cons: The eject tab is a bit weak. Be careful when ejecting and not to pull too much. The plastic on one of my tabs broke. I had to superglue the little peg back in place. Future versions should make the plastic holding the metal rod more durable.

Pros: great for using 3 hard drives in 2 optical bays. fan provides good cooling, loud fan can be exchanged for quieter one. fan filter is useful for keeping out dust. door for fan filter is good, better than other similar items that require sliding a cover out. holes are drilled accurately and hard drives fit right.

Cons: fan might be louder than expected, door appears a bit flimsy,

Overall Review: works great, good price, would like to see a 5 drive, 3 bay version or one incorporating 2.5in drives

Pros: works as advertised, no issues, timings were reported accurately,

Cons: none

Overall Review: working in ASUS m2a-vm w/athlon 64, did not overclock,

Overall Review: own a dozen of these, no issues, all temps register the same and they function as normal

Pros: no issues. works like its supposed to.

Cons: none really, works as advertised

Overall Review: nothing special, standard stick of memory, did not overclock and had no issues.

Pros: This fits 2 laptop sata drives in the space of an external floppy or hard drive. Trayless so no tools or trays needed to insert the drives. Looks sleek. Good for backups and swapping drives.

Cons: It uses a somewhat special cable for power and sata connection. It could be a problem for tight fitting cases or if the cable gets lost.
