Hiya, I have tried them and not got on with them. I find the tips are slightly thicker than normal ones so when you cut them they can get stress fractures in them which eventually become big cracks. I was told to make sure I had a sharp tip cutter, but had the same probs with a brand new tip cutter. I guess it must be me coz as you say they are every where. Also you have to be really careful with your filing so you don't file the design off, and they don't look so great when they are growing out.
