QUICKLY DETERIORATES AFTER A FEW USES!

LAST TIME EVER using these cheaply-made GUM Moderate (red) proxa-brushes. Something? changed months ago in manufacturing these brushes because the plastic fibers now loosen from the wire core and get in your teeth & mouth. Totally starts disintegrating after about only 5-6 “light” uses. And is irritating in your mouth let alone swallowing some plastic when they deteriorate. Already returned a used pack to GUM as requested for their analysis and, true-to-form, no response from them. DON’T WASTE YOUR MONEY BUYING THESE DEFECTIVE GUM BRUSHES!
