Pros: One of the cheapest esata enclosures you'll find, great when it actually works.

Cons: Look through the reviews and you'll find that these units have a very poor power supply that causes drives to intermittently drop. It's unfortunate because everything else about this product is great. I already had this RMA'd within the 1 year MFG warranty (had to pay $30 out of pocket for shipping) and the new one is still having the same problems. I would not recommend this to friends because of it's reliability issues.

Pros: Works great when it needs to, never issue with speed bottlenecks.

Cons: Seems to be dropping my 1TB HDD quite often now (HD103SJ). I've never had this issue before this week. Drive light doesn't always come online after the 1st power-on try. From looking at reviews, it seems to be a common cheap power supply issue. Aside from this, I've been in love with this drive.
