Stable unit with small defects

I borrowed the slightly stronger K4 bought (for domestic use), because I had to be negative the assessments of K3. The unit arrived (as usual with Amazon) very quickly with us and the price was by far cheaper than ebay and consorts. The assembly was doable with a little skill and the hard plastic parts made a really strong impression. The Stromkabelaufwicklung makes sense because one has when stowing the device is not constantly "collect" meter long cable. The handling is very simple and my two children 9 years old knew immediately where the device must be switched on. The plug connections are tight and make at first glance a stable impression, at least not dripping. I had bought the unit in order to free my equally bad painted garden table of old, peeling paint. Then came the disillusionment and a little insight that I had better bought an even stronger unit. I had previously from Aldi a smaller, commercial "King Craft" compressor, which has built up more pressure, despite less power. So I was a bit disappointed. In order to free a vehicle / trailer / Garden furniture from dirt and dust, the device is sufficient. Maybe I just expected too much.
All in all I am but happy with the high-pressure cleaner. Positive I noticed the construction, handling, assembly and processing. Even turning off the Komressors after short time of not "splash" is beautiful. The cable storage is also attached to a location that makes sense to me. Only the slightly too weak pressure has let me down (from hence one star less). As already mentioned, for home use is the K4 quite alright.
