If the blade is completely new, but makes this Hydro Depot for some smear (or how do you call it) on the face or the region to be shaved.
This is but the dishes away quite easily.
This deposit unit is a bit "low". Therefore you have to take good care of the beard approach below the nose, not after a few days to rest a hair "bart" forms there.
(BeimHydro5 apparatus can deposit this unit highly or fold down. Therefore you can with this, shave off such approaches more precisely. The locking mechanism of the blade to the apparatus is very well done and is totally "easy".)
Buy recommendation because Hydro 3 as Gilettes Mach3 Excel apparatus and Überkingen is significantly cheaper.
I wanted to add: The Hydro3 blades fit perfectly into the Hydro5 apparatus. Therefore, you can start, as newcomers, buy the Hydro5 apparatus and can then späer on blades offers - commercially - sent react. Take the blade that is on offer.
