Query: Great for what it is built for, which is a well built power strip

If you want professional power conditioning this is not it, but that is not what it claims to be. I have two of these and love them on my music gear. One is in my home studio and is used for all my amps as a convenient way to power them with some protection. The extra long cord is an excellent feature. I have a second one that always goes with me to gigs as a nice long extension cord with protected outlets. Again, if you want true power conditioner you need to buy one as this is not it...but don't dis this item. It is great for what it is built for.
