I think it has two things that make it somewhat unique.
1. Its got the hanging hook idea down pat (i know, this has been done before, but not all that often).
2. It has preset vent settings, which probably makes it easier to use and more consistent.
No, these are not brand new groundbreaking ideas, but they have been put together with some thought into a nice little package.
Also- the sale is going on til the end of January.
