I love my red snappers. They're super easy to use and if I get halfway through a quilt and want to work on a different one it's no big deal. Just a few seconds to take off the one i'm working on, a few minutes to load the other one and good to go! The only con is that sometimes if i'm working at the very top or bottom of a quilt my machine may 'catch' briefly on them but it's nof nearly enough of an issue to not use them. Go ahead and order them - you'll wish you'd done it sooner!
