Review (5/5): Quality product at a reasonable price.
I have had this toothbrush for 4 months and love it. At the same time that I bought the toothbrush I also bought the 4 replacement pack of brush heads from US HEALTH TESTS thru Amazon.com, not knowing that the replacements were generic. At 3 months I replaced the original brush head (which was performing great) with the generic replacement. After a week it became so loose that it pinched my tongue and lips. Installed the second generic replacement. Same problem. Contacted US HEALTH TESTS and explained the problem, they sent me a new generic replacement 4 pack at no charge. I am on the first replacement brush head of the second 4 pack and am having the same problem. This is one of many reviews with the same toothbrush head replacement problems, which causes me to ask Amazon.com and anyone else that may have the answer "WHERE CAN YOU BUY ORIGINAL REPLACEMENT BRUSHHEADS FOR ORAL-B ELECTRIC TOOTHBRUSHES"???????.
