Works well and powers well even without the power supply

Power supply doesn't power the unit.

Be sure to test it in store before leaving.

My IMAC does not have enough USB ports for what i need, second i have a few devices that have only USB 3.0 and wont work. It never dropped signal once for me and all the devices connected work fine and fast.

Difficult to fix onto to things. Power cord shouldn't be needed if I connected it to my computer. Need to press USB firmly into the port to work.

I don't understand the complaining behind this. It works great for me. Maybe people don't understand how to plug in USB ports.

I've had two of this model for over a year. I use the all-in-one they are attached to several hours every day. They have been entirely reliable. Though I haven't explicitly tested the data transfer rate, it is good.

The ports are upside down, i.e., the logo on a USB cable faces down when plugged into a port. Not really a weakness, just a detail to keep in mind.

I'm very satisfied with my two hubs. I may buy a third for my laptop.

- nice if they worked - It will charge your phone.

- Won't see phones or USB drives.

bought two of these for two computers they get recognized by the PC. However my flash drives won't work with these. Will be returning them...

Excellent USB 3.0 when it works

Totally unreliable. I used it with my IMAC and with my PC. In both cases it drops the connection very often. Practically useless.

Stay away from this one. It's a waste of money!

Seems to work as advertised. Have had the unit for months without problems.

I haven't found any.

Does what I need it to do: provide extra USB 3 ports.

When it works, true USB 3.0 speeds for data transfer

-Rarely works -Drops devices often -Windows very often complaining "a USB device has malfunctioned" -when you rely on a hub to "dock" multiple USB devices to an ultrabook with only 2 USB connections, you cannot have your mouse, keyboard and other peripherals like flash drives, backup drives, etc coming online and offline (offline more often than online) constantly - productivity killer

-Maybe I got a lemon, but this DLInk hub malfunctions often leaving me without my USB peripherals when "docking" to an ultrabook. Throwing this one in the garbage and replacing with a different model... ANY other model

If I could give this 0 stars I would, flaky poor USB 3 connections that would drop a drive if you even slightly bumped the hub. drives were continually dropping off the computer because of this hub :( months of agony thinking it was my hard drives, now finally realizing that the hub was a piece of garbage and is now in the garbage
