Bestart 3-Port USB 3.0 Aluminum Hub with SD/MS/M2/TF/Micro SD Card Reader (Black)

Doesn't include power supply adapter and the 5v dc port doesn't fit a standered 5v dc adapter. It needs some special big size 5v dc adapter that doesn't seam to exist. I looked online and couldn't find one. Tried some of my backup 5v adapters that meat all the spec requirements but they were to small to fit the 5v dc port.

Not always recognized by several different Windows 10 computers or "failed to install properly," or unit recognized but memory devices installed in it are not. right hand slot made USB drive very, very warm. Will be returning the unit.

Its a great product, except none of the USB ports work without an external power source. which mine did not come with. so its practically useless. I'm quite disappointing to be honest. however in terms of build quality it seems well constructed and properly labeled. so its not bad you just need an external power supply. and i'm not sure what it needs.

Missing all but the unit itself.Thus I got a box and a box within the box.I did not get a cable for USB 3.0 and I did not get the power supply as this is a powered device, which when I purchased this was not mentioned.

Works perfectly, exactly what I wanted. Cord was the perfect length to run down my desk into my pc. Makes it far easier to plug in SD cards and the like now.

I returned this item. It was not what I expected to receive. It is very small and did NOT come with a power supply.

I got this, opened it up, plugged it in an nothing. Do yourself a favor and buy something else. At least I got a refund.

I inserted my SD card and it did not work. I tried many times, and finally it worked. I tried it again, it did not work. It also requires a power supply in order for its USB ports to work. It's a dud.
