Okay, I'm nowhere near an expert so take it for what it's worth. I liked this tool and was able to master it pretty quickly. My wife hates this. I did NOT use the corner feature as I don't use mesh tape in the corner. I ALWAYS use strong paper edges in the corners. But I think I'll try the trigon function just to see how it would work - I got curious all of a sudden. Overall, it was worth the price for the convenience of direct recording alone. Much easier than rolling and pressing/cutting by hand. Don't listen to my wife =D
