I wanted to get a power strip that has surge protection and as far as I understand it, this one does. I am not really well-versed on the electrical engineering side of things, so I just "believe the packaging" that it'll help protect computers and synths "just in case" something bad comes down the power line. Yes, I have two now, one for the computer table and one for the synth table. What can I say? They are well-built, ostensibly "Made in Germany" (unlike others from the same company), and do what I need them to do. I wish they had a version with sockets that rotate? And if I could figure out how the heck the mounting brackets are supposed to work I'd have given them all the stars.
