Review (4/5): Best and Best-Buy Electric available today
In spite of the fine reviews, when I ordered it I was skeptical. I'm a believer now. I also am always skittish when I hear of a product that tells you "time to buy more".. :)
Also the purchase of replacement heads CAN be reasonably priced IF you buy it from amazon rather than a vendor that needs added shipping AND you plan ahead to fit it into another purchase so you get free shipping (or even possible discounts). They are currently priced about $15 for 3 and that seems reasonable. (or you may find them at a "store near you" at retail price which I would expect to be similar).
PRO:
*The DUAL CLEAN provides excellent cleaning.
*For those with small mouths or special needs there are other heads available for whitening, flossing, soft bristle, and single rotating
*The battery SEEMS to be pretty long-lasting (based on others, I've not had it long enough to judge)
*reasonably priced and available head replacements
*the built-in 2 minute timer is also a nice feature
*the charger is small and functional (too tall for most medicine cabinets..). The cord is plenty long.
*Its easily rinsed
CON:
*The rechargeble battery SHOULD be specially disposed of (think green)
*The dual head is fairly large.. its fine for me, but for children or small mouths I expect it would be uncomfortable (use a different head style)
*The "buy now" color-change bristle seems to vary only with time, not use or bristle flexibility.. It is pretty much just a marketing gimmick.. buy a new one when you think you need it instead.
I've examined a number of electric brushes (and have owned a number over the last 30 years) and I believe this to truly be the best on the market to date.
edit 7/'11: The price on this has gone up almost $12! This is a 66% increase in a year.. There has been no retooling cost .. they are just milking a cash cow now.. I still like the unit, but the price is getting out of hand... no longer a "best buy" from me... it still is a very simple device. The replacement heads are now about $6 each.. up about 20%.
