But powerful pump quality plastics and assembly perfectible

This is my second purchase after the ex K.6 whose pump failed after six years. I'm just surprised it K7 proudly touting its German manufacturing, offers plastics whose assembly is approximate. The one in front by example does not fit fully in his seat, one end has a great day. Another thing, if you pull down the pipe spear without holding the device close, you get a tilting front of it. Impractical to use if you do plan to take the tube to length before starting your work. Karcher engineers should perform some tests before he might understand how using this type of product.
These are the reasons for my deep disappointment
