I've worked with it a few times, and once you set in place, it doesn't want to move to freely. It's definitely good adhesive, so make sure you do it right the first time.
Also, if you're curious about the look, any BestBuy or CircusCity

has speaker boxes covered in almost the same material. I'm willing the gamble though it's just as comparable as the vinyl from Happs.
It's only going to be as neat and durable as the application. It's like applying sideart, the more you lift and resposition, the least likely it is to hold up.
Cut what you need , for say..the side of your cab ... then peel and stick as you work your way down the cabinet side.
