Has anyone on this great board heard of/used this temp file cleaner? If so, how is it?

Found it at www.glocksoft.com/temp_cleaner/index.htm#top
After reading Dudley's post on registry cleaners. I've been using HD Valet for quite some time with good results. But it "does" leave stuff behind. Would like to try it, but would like opinions from folks who actually "have" tried it.
Thanks..
