Yeah it's certainly a strange looking thing, and that was the first thing I thought too, doesn't look too raised off the body, I'm sure I'll be able to get used to it with practise. Thing is too unique to pass up (and cheap!), however impractical a top loaded B-bender may end up being. I can't even find one with a B-bender like this on Google images.
EDIT: There we go, tracked down a similar one, might be from the same company.
