Reviewer: Expat in Chile
Rating: 4/5 Decent case but inferior cable. September 4, 2021 Cable that came with it fits loose in the port of the case dropping the connection even if moved slightly. Originally thought it was the connector on the board but trying two other cables quickly revealed the culprit was the cable.

Rating: 4/5 Inexpensive enclosure from a name I trust. September 7, 2020 I've used many different enclosures like this from various brands, and often they are of questionable quality and have high failure and DOA rates. This one has given me no trouble in the year I've owned it. Simple, inexpensive, and reliable. It is still made of plastic so it would be better if metal, but there are other products for that.

Reviewer: Krismo Location: Sapporo, Japan Age: 25-34 Experience Level: Home User Owned Product: less than a month
Rating: 4/5 Affordable quality June 24, 2019 The external hard drive was at a good price and I decided to buy it to have somewhere to store my school and work files. It`s basic, but my only complaint is the case it comes in feels a little flimsy. But it is very light and easy to carry with me on the go. Overall I`m very happy, and I don`t care about writing speeds, as long as I have lots of memory and writes at a decent speed. It also came with a small carry case.
