Unfortunately, the Kärcher is insufficiently protected in their original packaging, since the parts can just scrape together during transport already, as noted in other reviews. I had initially received a device (not purchased through Amazon), in which I had to find a break at the weakest point of the handle when unpacking. The damaged equipment but was easily replaced.
The short test run convinces by simple operation and provides sufficient pressure. The handling is generally well done, especially practical is the hose reel.
Unfortunately tilts the device with its relatively high center of gravity when rolling the hose to relatively easily. This is especially on my sloping driveway of disadvantage.
My conclusion: The K4 Premium Home deserves a positive judgment, am so well looked again for the next few years.
