Review (5/5): but I do love this little thing
Can't speak for the durability yet, but I do love this little thing.
Easy to change out, especially since you can just turn the speed dial down, unplug the cord from the dremel, but still leave the power cord it plugged into the wall, switch, and just pop it back in again.
I'm using mine on soft plastic projects and shaping acrylic nails.
