I. Love. My. Fein tool.  It has accomplished some tasks that I doubted could be done, in renovating a 100+ year old home.  Some have found the blades don't last well but they have for me.  I'm going through hard heart pine with big nails and do chew up the teeth on some blades but, considering how much time and aggravation they've saved, it is well worth it.  I don't do that kind of cutting  with this flush cut blade, of course, but it is one of those tools that, when you need it, you need it and there's not a very good substitute except for expensive flush cut hand saws.
