Using this toothbrush takes some getting used to because it's wider than your average toothbrush. The bristles are also softer than what I'm used to. These are bad things though. After I use this brush I feel like my teeth, and especially my gums, were cleaned extremely well.
We bought these toothbrushes as stocking stuffers. There is a sticker on them that tells what they are made out of.
My roomate and I just got one of these Radius toothbrush and we absolutely love them, the handles are comfortable and the soft bristle feel fantastic and on top of it I think they look great.
