I purchased this shaver in September 2013. Initially, the results were quite acceptable but recently they have deteriorated to the point where I am seriously considering replacing it.
This shaver is nowhere near as good as my old Panasonic ES8249 which had a linear motor.
Age and the batteries failing to hold the charge forced me to replace that unit, how I wish that I had gone for another Panasonic.
Very quick delivery; 1st shave this morning was excellent.
Good price, absolutely delighted
I thought it was time I replaced my old Braun 8000 series razor and so opted for the 590cc-4.
Although I've been using 5 series blades and shields for some time I can't believe how much better the shave is with this new razor.
Like a previous reviewer the only reservation is the hidden cost of the cleaning, but at this price the saving more than covers even this.
