Pros: Worked great for one month.

Cons: after 1 month the power supply died. Replaced with another of the same voltage. Now after 8 months, the entire box died. Very Poor quality! And it's powered by an APC UPS so it was NOT a power surge. I'm very disappointed.

Pros: works

Cons: The device claims to be 64GB, but according to DISKPART it is only 57GB or 61,203,283,968 bytes. At first you might argue about formatted -vs- unformatted capacity, but I bought another 64GB flash drive of another brand, and it measures 60GB or 64,424,509,440 bytes using the same utility. That is an difference of 3.2 billion bytes!! I also checked for hidden partitions on the drive; there are none. Not sure about reading, but when doing a full format on this device it gets quite hot too.

Pros: none yet

Cons: Just received this device and have not powered on yet, because I can't. The unit requires an external 5V Power Supply which is not included, and there is no mention of this on the product page on NewEgg. I have power supplies, but this requires a tiny (non-standard) barrel connector that I don't have. This probably explains why others are complaining about some features not working, because the 1/4 page document that came with it says you need external power for some features. It's a 5 port switch, but the box is labeled 3 ports, and while they meant to label the box "digital switch" it is labeled "Digtail switch." Digtail? Sounds like a breed of dog. Isn't it great buying things direct from China? I am very disappointed that I now have to go buy power connectors and spend extra money before knowing if this thing even works right. Buyer beware.

Overall Review: I was attracted by the low price -- big mistake. Next time I will pay more and read more reviews before purchasing.
