Controlled irrigation is different.

Video at Amazon.com See When Gardena 8125-20 Oscillating Sprinkler piled up well the discomfort due to massive quality problems.
Obviously Gardena reacts now and it brings a newer version.
Who flirts with the old part, should look at the video. Protagonist is a brand new sprinkler directly out of the package.
This unit has a predetermined breaking point, which is already leaking at the neck and uncontrolled irrigated in the reverse direction. It's just a matter of time before the plastic neck going completely broke.
For me, a clear no-go with immediate return of those parts.
