After usual instantaneous Amazon delivery I've tried to hose directly. The tube is sealed - in view of the fact that it passes through the half apartment including living room with parquet, not unimportant.. You have to make sure something which is exposed to the hose kinking. If the water pressure is high enough, but that is not a problem. The ports function as expected from a brand manufacturer perfect. It is supplied with a spray nozzle.
The cassette and the "mechanics" to roll up the hose are miserable. The knob for cranking can not lock themselves and you have him permanently in his hand - botch its finest! I'll probably remove the black part of the rolling out of the cartridge and use individually. The rest I dispose of then.
There are products from competition for 20! Which make it even worse ...
