Low quality [SEP] I was suckered in by the seeming bargain of these brushes, but they really stink. I've used one for about a month now and I'm just about to switch back to the legit Oral B brand brush heads. I can be thrifty in many areas, but I can't afford to cut corners with my oral health. I've spent too much time and money keeping my mouth healthy.<br /><br />These heads are smaller than the name brand and they don't cover as well. When I'm done brushing, I feel like I need to start over and get after some of those tough spots again. I've really tried to give these heads a chance, but they just don't measure up.
