It's no different than builtak and a lot of the other printing sheets.  Personally I don't like them.  They stick too well at times making it difficult to remove the prints.  The sheets themselves are also very thin (3 mil) so you'll end up with either ripped/torn/cut sheet which you'll have to replace or you'll break the glass.  I guess that's why they come in 3 packs.
