This is a really good low cost basic Oral B brush.
I just recently purchased this brush and have been very pleased with it. I had always been reluctant to spend so much money for a toothbrush, especially since you can now buy the battery powered ones in drug stores or grocery stores for sometimes less than what these replacement heads cost. However, I find that I do get a deeper, better clean with this brush. My teeth and gums feel healthier and more refreshed and I'm more likely to stick to a better schedule because the 30 second timer per quadrant adds up to 2 minutes total and this is a lot less time than I usually spend with a manual brush. I've noticed that my teeth are whiter in the few weeks since I've switched to this tooth brush and my gums look and feel more healthy as well.
