'The Rippity do-da is the new must-have for your sewing. Make the task of taking un-sewing quick and painless with the Rippity do-da. Simply glide down the seam the same way as the old fashioned seam ripper but in a fraction of the time. It's quick, easy and it won't poke holes in your fabric or you! Use the enclosed mini lint roller to simply whisk away the thread left behind.'
I've been seeing this around lately and keep thinking about getting one. I have the little lint rollers and a ton of regular seam rippers (I need plenty). If this would make ripping out easier and faster then it might be worth it.
I think what I like most about it is the name, every time I see it it sticks with me like a song.
