I love this kit. I tried it right away and was very pleased with the result. My only problem was the packaging. When I was finally able to get the plastic clamshell open, the tips went flying. I found the fine tip and the heavy tip but still can't find the medium tip and I looked for an hour. I really do hope it shows up but given the state of my craft room, that may never happen.  If you haven't opened yours yet, be very careful and you shouldn't have any problems.
