Samsung DVD Writer,
Verified Purchase(What is this?)
This review is from: Samsung Super WriteMaster Slim External DVD Writer USB Powered (8x DVD / 24x CD) - external - black (Personal Computers)
I purchased this because ultrabook laptops do not have DVD drives. There was no problem with installation despite having in theory to plug into two USB slots which would have been impossible with my laptop. It worked with just one plugged in. It does exactly what I wanted: I was able to install software from DVDs. It is light but sturdy and therefor very portable.
