5 out of 5 eggsWorks great for less than $10

Pros: It works. Its fast. Its decently constructed.

Unlike some external enclosures I've used, it works fine with USB 2.0 using only one port. No need for the two port Y cable, or an external power supply.

Cons: Yes, its plastic, and no its not as solid as an aluminum one. I take that as sort of expected at this price point.

No instructions. Its simple, but not intuitive how to remove. The person here who posted this really saved me from this being frustrated. With this hint, its very easy. "The cover will slide off towards the light.(On the side with no plug in)"

2 out of 5 eggsCheap and Flimsy

Pros: Connects reliably and and data moves quickly using USB 3.0. Very cheap on sale.

Cons: Flimsy construction. Drive cover does not come off or on easily due to it's odd shape and retaining mechanism. The cover does not fit very tightly either, and I suspect that it won't last long if removed often.There are no real instructions, and it is not obvious how the cover comes off. The retaining tabs could easily be broken if pushed too hard in the wrong direction.

Other Thoughts: This item is functional and nice enough looking for $10, but there are other cheap enclosures that are a bit better. The Orrico has a better fitting cover and is slightly smaller overall.

4 out of 5 eggsWorks Well

Pros: Low price; Works well.

Cons: Sort of cheap appearance; Hard drive clunks around inside case.

Other Thoughts: This HDD enclosure is ideal for when you install an SSD in a laptop and you want to use the old HD for external storage. Does the job well. The case holds the thinner 2.5-inch HD's, but not the older (thicker) ones. The HD was clunking around inside the case, so I used a couple pieces of thin foam to hold the HD in place: problem solved. Performance seems very good when connected to a USB3 port. I would buy this product again.

5 out of 5 eggsWorks as advertised

Pros: USB 3 capability, enclosure securely holds drive, indicator light shows connectivity/data transfer and price/value.

Cons: None

Other Thoughts: Purchased this item along with SSD, to clone my laptop's existing HDD via USB 2.

Worked as advertised (e.g. some USB 3 controllers don't downshift to USB 2 very well).

Although I did not need USB 3 capability this time, an excellent investment.for the future.
