I found this tool works great with my invisible alignment trays -plus it fits with my trays in my retainer case.
It does take a bit of trial and error to figure out how to use it. I found that hooking the trays at the very back, pulling forward and down works the best. If you have "buttons" on your teeth, pulling SLIGHTLY away from the buttons and down, instead of straight down, helps.
