radius - toothbrush replacement heads, for source and tour toothbrushes, premium bristles (super soft, pack of 2)

I adore these toothbrushes and got my family hooked on them as well. I love the feeling of brushing my teeth with The Source Toothbrush as well as the way it cleans my teeth!

I love the extra-soft and extra-large brushing head on these toothbrushes. These features allow me to massage my gums at the same time I'm cleaning my teeth. Being environmentally friendly is a big bonus.

The best toothbrushes ever. I was honestly a little surprised reading all of the bad reviews because I've been using this for over 5 years and have the same 2 handles, one for home, and one for travel. They have both lasted me that long. So I don't understand how other people say that their handles break or don't last, maybe they're just being too rough with it? I don't know. The other thing is, I don't have trouble with my bristles “falling off”.

I have now bought and tried every adult toothbrush and can say I LOVE them ALL!! The source brush is great with a sturdy handle and the soft flossing head works really well to get in between the teeth. It's a little too soft for my liking but easy fix to use a different replacement brush!! I appreciate the fact that all the brush heads are interchangeable. My fave combo so far is the source toothbrush handle with the big brush replacement brush!

Excellent toothbrush heads and it's wonderful that you can buy the handles separate. The handles are fantastic also. Definitely the best toothbrush I've ever had. This is a great company with environmentally friendly products and packaging. Thanks Radius!

I didn't want to stop brushing my teeth. I love this toothbrush

I love that this is made with recycled materials. The last one lasted about 3 years until the toothbrush head stopped securely lock, creating unstable top and toothpaste getting in the socket. So I bought the new one in different color.

I keep coming back to this toothbrush. Works well, soft bristles,gentle on my gums. Sometimes it's difficult for me to change brush heads,but I like the concept. Shipping is fast and easy order.

I suppose it you had dexterity problems, this handle would help enormously. I just find it a clunky thing that isn't that ergonomic, which I presume is the point? I am suspect that the snap-on brush will be a long lasting component, but I could be wrong. It snapped on firmly but plastic wears out so fast. Though I do appreciate the concept and it's the reason I bought it.

If it wasn't for the bristles falling out and stabbing your mouth, as well as posing a safety risk if swallowed, this would be my all time fave toothbrush. Great clean, comfortable, but I'm tired of fishing loose bristles out of the back of my mouth. This is my third try hoping it was just an anomaly; it isn't.
