I have used Oral-B products for 40 years and feel that they still represent the highest quality for oral care BUT at a price.
It is pleasing to note that whilst they still have "high end" products that they and Braun can produce a brush for the lower end of the market. The handle itself uses standard oral b heads and cleans my teeth well, validated by the use of disclosing tablets after use: I would say that with all of these products they need to be used properly to get teeth clean and disclosing tablets facilitate confirmation that you have cleaned your teeth properly.
In use, it holds its charge well and certainly is good enough to take away for a long weekend without the need to re-charge and in my case, represetns excellent value for money.
