What do you think of this device

30gb USB OTG, internal batteries, $109

Seems too good to be true.

As I learned from others regarding OTG, the card reader you use, aside from the speed of the card itself, greatly affects the copying speeds that you can get with it.

If you ignore the battery inside, it's basically an OTG PSD without any way of knowing that the copying is complete, let alone verify that no errors exist during the copying process. In simpler terms, it looks like my LOOK PSD, except that the LEDs and the copy button gets rearranged.

It's same as Welland Magic Box. Search this forum - it was mentioned here.

Thanks.

The device is actually advertised at $80 with a 30gb drive. Even if it is USB1.1 it wouldn't be a deal breaker at that price. Since I need a PSD for an upcoming trip next week I just ordered one. I'll letcha know if it works ok.
