Bought this to revive a 6 year old bathroom and was expecting great things based on these reviews. I wasn't disappointed. The applicator is rubbish (as others have said) so I removed this after a couple of tiles and used my finger to apply it instead.
It goes on quickly and easily and the excess is relatively easy to clean up. Don't wipe it off too soon though or you might wipe off the area you've just grouted too!
I've already recommended this to friends, which is a bit sad really. I guess I really am getting old now! :-(
