Review on 📥 Efficiently Duplicate SD & MicroSD Cards: Vinpower Digital SDShark Duplicator - 7 Target by Kevin Schnitzer

VINPOWER 11 TARGET USB DUPLICATOR, not recommended. It copies the main USB to the targets, but they all have to be USB 2.0 or USB 3.0, you can't mix. It's very slow. 4GB USB 2.0 takes 10 minutes. If a USB memory is defective / not good enough, the copier will stop. Sometimes the only way to stop it is to turn off the device. Doesn't always appear after shutdown. It gets stuck on checking memory or suddenly displays Chinese letters. after a few on/off it starts working. Another annoying feature is that you have to use the "Shutdown" button. If you don't remember to use them, there's a 50% chance you'll get stuck on the next startup sequence. There is no newer firmware and it looks like this company uses the same controller in many products (discs, CD/DVDs and USB duplicators).
