Bests & Worsts Reviews from Amazon

I can't think of anything negative to say about this product. I did a lot of research on Oral-B's products as compared to Sonicare before buying this unit, and I'm happy as heck with the choice I made. It's easy to use, easy to keep clean, very well constructed and is a very effective oral hygiene tool. Also, since my bathroom is small, I really appreciate the small footprint of the recharging base. When I was making the decision to buy this model, I went back and forth as to whether to go with the SmartSeries 5000 with its separate "Smart Guide," (as opposed to the only slightly-cheaper 4000) but I'm glad I opted to pay the extra money for this additional gizmo. Aside from the fact that it doubles as an unobtrusive bathroom clock, I actually find that the visual guidance on brushing times, brushing mode, and brushing pressure help me to use this product to its full potential. Also, in case you were wondering, the cheaper AA-powered brushes you can get for a tenth of the price of this product simply DO NOT COMPARE. UPDATE as of September 16, 2014: I am still using this product, and have had absolutely no problem with it. UPDATE as of December 8, 2015: The poor thing finally gave up the ghost. Still, it had a good run. I'm buying a more current model.
