I bought this unit because my other razors are still too expensive. But I am absolutely thrilled and do not regret the purchase. The dry shaving is a bit of getting used to something more to "press on" has, but the most fun I wet shaving. Nice lather and then slide the razor almost goes over the face. I am very pleased with both results shaving (dry / wet). The charging time is short and I come from more than a week on a single charge. However, the best thing is the cleaning. Remove only the shearing blade and keep a few times under the tap and everything is clean - perfect! For this you need no expensive cartridges.
