The razor I used before was a quatro manual razor for not cite, as a tester, I was able to try the razor BRAUN 720s, I seized the opportunity and I have to say I was pleasantly surprised by this. This shaver, technology based on a straight razor cartridge (provided with a double grid) can easily bow which gives a shaving efficiency much greater than many razor. He shaves well, even the long hair, does not irritate, cleans up easily (and water, and more), long battery life, it has some useful accessories (cover, brush ...) The unit is supplied with a cord long enough for a direct connection using the sector. I highly recommend this razor before testing javais this one had an electric razor, but I have not been convinced of all, while the clean very well and very good battery life.
