I absolutely love this toothbrush! I started with the manual version because I wasn't ready to spend $100+ on the electric one until I knew I'd actually like the design. Now I'm sold! It reaches all the little creases and hard-to-clean areas around my teeth and along my gumline. My gums were a little sore the first couple of days, but I realized that was because it was cleaning areas my old toothbrush wasn't reaching. Now it honestly feels like a gentle gum massage. My mouth feels incredibly fresh after every brush, my teeth feel super clean and smooth, and I've even noticed they look a little whiter. The quality is amazing, and I'm so impressed that I'll definitely be upgrading to the vibrating version when it's time to replace these.
