The trimmer also works very well. I'm curious to see how long he keeps this time. In my Synchro he was broken relatively quickly. but that the normal shaving performance has not deteriorated. In direct comparison to the Synchro - which is not quite fair, because it was located in a completely different price class - the shaving performance is better, but that can be expected from a new razor sharp shaving foils also. What I do miss is the lateral vibration of the razor head. This hair was better recorded and you had the feeling that the razor glides easily over the cheeks. However, the price gap for 7 Series was too high for me. If I aufteile the Surcharge to 10 years or to the more than 3,000 shaves that has kept my Synchro, I regret it but a little to have not yet resorted again the top model.
Conclusion: Good device-level price class. Who can afford it, however, you should pick up the top device.
