Query: Waste of money

I bought this to make a Valentine's Day shirt for my daughter. The plunger would not spring back the way it is supposed to so each time I wanted to set another gem I had to take it apart, pull the spring apart, then put it back together and load another gem. Finally, I decided it was easier to just push the gem in by hand, and bend the prongs in with needle nose pliers. After spending two hours making the shirt, my daughter wore it once. I hand washed it, and the metal on the gems rusted onto the fabric. Ughh, nothing seems to get rust out, so it was a big waste of my time and money.
