My old shaver looked exactly like this one, but the brand was Generation. I think that it is manufactured by the same company but is branded by other companies for resale. I got it free after rebate and used it for like 3 years, and it was still going. The battery life was ok. The shaving was ok, but not close to the skin. So you won't get a very clean shave. The trimmer does not last very long, it is not sharp enough for endure many time of usage before it is not sharp anymore for trimming. But it is quite good for a backup shaver.
Now, I am using Braun 7526 shaver and I got a much better shave.
