I have almost wiped out on this board several times, then I stuck this wobbler in the donate pile and bought a wooden, square one. Now I don't have any issues staying on the board while I wobble. I wish I had just ponied up for the square one from the get go. The plastic round one may be fine for someone who is awesomely in shape already, and possesses cat-like reflexes, but for people with bad knees and arthritis, who may not be able to react quickly enough to catch themselves from falling when this board slips.get the square one.
