Review (5/5): love it! would buy it over and over.
had this same one for 7 years. love this thing! i've traveled with it without the charger at times and to my memory, a full charge lasts me at least 3 days! it's slim and attractive and really the whole things is quite portable for travel as well. i like how well priced it is as well as the prices for the replacement bristle heads. and honestly, i've had the same bristle for years and it quality has only moderately degraded with time. the machine component/handle works as good new!
also, if you are good about actually brushing your teeth for as long as you should - your teeth get pearly white within a week or less!
