I like the larger headed toothbrush head. It makes my teeth and gums feel cleaner and seems to get more debris out. Really like the way it makes my mouth feel cleaner.

I think it's a bit soft. I haven't used the smaller head yet, but the bigger one just doesn't seem to be firm enough. It's still a good toothbrush, though.

As a periodontist, I can honestly and truly say this is the best machine ever produced! It is easy to use and very effective for clean teeth and healthy gums. We are truly blessed.

Questionable on how long they will seal when having to change several times a day when two people share the same handle, as in a family setting. Way too expensive and space consuming for multiple units.

Feel that this brush can reach all spots and flossing works great, but believe that brush it self can be more stiff, these flexible brush threads lead to more brushing passages and more wear, hence the 3 months advised replacement period.

Still evaluating compact vs regular size brush. Very comfortable and gets the job done. Unfortunately, very overpriced. Difficult to clean toothpaste out of either brush.

I had read and watched videos that made me skeptical, but these work well. I hated my regular water flosser with a passion - but not anymore using this product an these brushes.They are a bit expensive.

I appreciate the great value of 6 Waterpik toothbrush heads verses what I would have spent on them individually in another store. The shipment was well packaged and arrived quickly.

These are what they are supposed to be. No knock offs here. Great deal.

These full size brushheads are more effective than the original compact heads.
