I have this dryer and it works very well. I haven't notice a change in my electric bill at all. In fact, I live in an older home and my tabletop dryer would sometimes blow the the fuse, this has not happen at all with this dryer.
I didn't get the wheels because of limited space. So I place it on a box for height and when I'm finished I take the hood off and store the hood and dryer in the original box that I hide in a corner.
The brand I have is Venus. Hope this helps.
