This seller seems to come up with these on more than one occasion.
Of course, this one showed up two week after I got my used Icon with Tech Tool. In the meantime I had replaced the display and bought a 5th tip.
But I did what you would do, I bought the damned thing.
If you are in the market and can wait, watch this guy.
