Pro:
Small charger
Great Design
Easy to handle
3 degrees of hardness
Powerful jet when freshly loaded
High quality optics and top processing
Contraindications:
The tank reaches only max. 30 sec.
Battery loses if not daily load quickly force.
Water jet only hard when battery full.
The on / off switch engages. (On or off) would be nice, a pressure switch for short splashes.
My overall rating:
Overall, the device convinced me.
Space-saving and convenient.
I would buy the unit back
