Ok, finally tried it out. Here's my opinion just incase I'm not the only one out there thinking the same thing I was..... 1) True, messy as hell and theres no way possible to get into every nook and cranny and get all that paint out, even soaking don't cut it..... 2) To get a nice point at the end of your stroke, you have to turn it up on the side of the wheel and gradually lift off. This is going to take alot of attempts to get it right..... 3) I could see how you could get stutter at first, I resolved this by doing a few strokes first on some paper then wiping off any access paint that seemed to thick from the sides of the wheel..... 4) joining lines wasn't to bad at all, added a few drops of reducer to the paint and it flowed right together..... Overall, If your doing a large job that is all the same color, go for it. If its a job that you plan on using several color combo's, don't even pick it up. My opinion, If I had to pay what their asking for these new, I wouldn't.
Hope this helps
