Query: Beware:clean and renew base can be defective

This Braun Shaver provides a close shave (except on lower neck), is constructed well with a good charging time, and is worth the money. Unfortunately the cleaning base is not. The cleaning base's metal contacts creep back into base and do not provide a secure charge! Even after taking base apart (which is risky, since the clean and renew base is constructed very flimsily and its' shoddy plastic components can easily break) the metal contacts will recede into base and you will not be able to charge or clean shaver without buying a new clean and renew base, which costs about sixty dollars. The shaver is excellent build quality, made in Germany, but the cleaning base was outsourced in Hungary and is very poor quality. I think Braun needs to really put more effort into constructing a quality clean and renew base for it's fine shaver. Otherwise, this shaver is definitely not worth its' expensive price tag.
