Love Aqua Sonic! These brush heads really get your teeth squeaky clean!

Much better than the original brush heads. I felt like my teeth weren't clear enough with other brush head. While looking for a new toothbrush, I found these. They bigger, has more bristles AND the center bristles are more firm. Love this toothbrush head and now I dont have to buy a new toothbrush.

The standard heads that come with the black series (non pro version) are a bit too small with fewer bristles providing less coverage when brushing. The standard heads are also a bit too soft and I can feel the tips aren't rounded out so it's also poky. The Proflex brush heads are the solution! Proflex heads are larger with more bristles providing more coverage and the bristles are much firmer (like a soft-medium), and the tips feel rounded out. I also prefer the 'w' shaped bristles of the Proflex over curved shaped bristles as I feel the 'w' hugs each tooth for a more effective clean. I also get a better clean when brushing my tongue with the Proflex over the standard heads. My one request is that the company add a silicone layer to the back of the brush heads to cushion our teeth; the sensation of my teeth hitting the hard plastic while brushing is uncomfortable! If this change ever happens I'll update my rating to 5 stars.

These replacement toothbrush fit well and work perfectly.

Very nice replacement heads

I did get this in addition to my new toothbrush, simply because the brush heads are a little bigger and does a better job at brushing teeth. They’re soft enough but not extra soft as I wanted. They do work for my needs and it’s worth getting the larger pack! Price at the time of purchase and review 29.95

Size isn't a whole lot different than original brushes. But big enough to feel the difference.
