The Philips AT620 is a wonderful appliance if you want to give yourself a clean look everyday.It provides close shave like a normal metal razor( though not a complete clean) and the best thing, we can also use it with shaving gels and foams.
The major advantage of this shaver is that it is waterproof, that makes it easier to clean.The electric shavers are a big advantage if you are continuously traveling or are in a hurry.
Also, it has 3 years warranty, so sit back, and relax. The only drawback I felt was that It takes a good 3-4 hours time to recharge. So you have to be careful of recharging it when you are out traveling.
All in all, I would suggest to go for this one without any second thoughts.
