I have the Simplicity electric strip cutter. Like Bella Boo, I have used it mostly for cutting strips to make fabric bowls. It works wonderfully for that purpose.
I have also cut 2" strips for quilting with this machine. It works okay, but only if you are willing to go very slooooowly. If you try to cut fast, the strips wiggle all over the place and you won't get accurate cuts.
Now as for the Simplicity Bias Tape Maker - that thing is pretty awesome! I use mine all the time... love it.
