Five Stars Great for wipe boards when you need to draw a cirle.
terrible I could not get the fixed point to tighten, ie , did not work, not at all,Looks like a defective design or I have a defective one.getting tired of defective parts from Amazon
Sucky suction cup Makes great circles but the suction cup that holds it to the board broke and I can’t find a replacement that fits. It should definitely come with a few replacement suction cups or at least information on how you can order more. I love that it accommodates both fine and chubby tipped markers by simply popping out that piece.
