Because last year is once again gone a sprinkler of "market leader" broke, I decided a sprinkler from Kärcher to buy. This is in my garden since 04/12 in use and delivers top job! Now I have the OS 3220 again ordered me, as I do not get along with my garden with a sprinkler! I would recommend this product the brand Kärcher buy back any time, since it delivers for that price Top work!
