Review on Efficient USB Cloning and Erasing with StarTech.com 1:2 Standalone USB Duplicator and Eraser (USBDUP12) by Hassan Tomlinson

I bought this about a year ago to duplicate some of the drives used as boot systems for our technicians. The original discs were from Kingston and I bought the same ones for copies. I thought I had a bad block as each copy failed. After replacing the block, the replacement did the same. Finally, after working with their tech support, they informed me that they were aware of an issue copying to Kingston drives. I switched to a different brand for the target drive and had no problems. It would be nice to know this in advance. Had asked support to tell me about software fixes to fix the problem but never got a response.
