Brittle plastic [SEP] There are not too many options for something like this.<br />I wish they would make it out of better material.<br />The plastic is cheap and brittle. It cracks if you look at it the wrong way.<br />The disc isn’t even secure on the wand. It easily skips off and will crash to the ground and crack.<br />The cover cracks quickly if you tighten it too much. Even a little too much.<br />They should have made this one with a more flexible, durable plastic or rubber.<br />The beads are cheap plastic too.<br />Most of them don’t even roll. They get stuck.<br />But, as I said; there aren’t too many other options for sale. Other similar  units are sponges on sticks. Sounds awful.
