It already doesn't work. I bought it in January and now in April, it will not work. Waste of money.

This is a good product.

This just flat out doesn't work!

So far its been a life saver, even works on usb2 ports without extra power, love it

This product was HUGE for cutting down my weekly tasks. It probably cut it in half for the first couple of weeks that I had it. But after a couple of weeks it stopped working. I will plug in 4 memory cards and some will register to my computer and others wont, there's not a consistency with the ports that aren't working. I've tried blowing the ports out to get rid of dust, but no luck. Really just sad because I loved using it.

I plug this device into my laptop, plug a USB flash drive stick in. The window for the stick appears, I open a folder, I highlight two files for transfer. The window closes. I retry on the #2 port on my laptop, get just as far, the window closes. Then three copies of the USB window open within 1 second of each other. I tinker around with it in different configurations for 5 minutes,trying to get enough time to transfer a file. No luck.This device is a waste of money and doesnt even function right out if the box. I am throwing it in the trash, sorely disappointed, because I really need a transfer pod like this.0/5 stars

It continously ejects my SD cards & Thumbdrives. Makes it a hastle to use.

When a card is inserted on one side of this device, it gets popped out slightly when another card is inserted on the opposite side, and neither card can be accessed for data downloads.

Muy buen producto y buen precio, la calidad es muy buena
