Enclosed times a brief comparison between the Gardena and the Wolf garden. I've also uploaded some photos.
I've bought these scissors in Bauhaus for 9.99 euros with us. My old Wolf-Garten Hand Grass Shears Rotary (there are here at Amazon for 11.89 euros) has for many years well their services has been done over time but unfortunately dull (stones are just a bit harder ;-)
Grinding was not worth it and that's why I picked times to the Gardena. A more favorable I had not found in the Bauhaus.
Personally, I find the scissors high quality finish. OK, it's not metal like the Wolf Garten and the rotatable Gardena Model also costs a few euros more, but I get along well with the scissors.
On the handle top it is unlocked. The handle can be squeezed together pleasantly and then springs also slightly apart again.
It is slightly lighter than the Wolfgarten as it is from the grip her plastic.
I use it mainly to cut my grass edges in maps. And since they did not let me so far down.
It all depends on what you need it is always such a pair of scissors and how often you use them. For 4-5 times a month a Bissel in the garden what to cut, it is absolutely sufficient.
Professionals will naturally resort to high end device.
Now of course the question arises as to which one should grab grass shears. The Wolf Garten has the advantage that it is made entirely of metal, this can be the cutting blade up to 90 degrees adjust (I have this function but never used). That's a little difficult to move, but they will then remain in this position.
In weight it is slightly heavier than those made of plastic of Gardena and of the cutting blade lengths here are almost identical both. The Gardena is through the longer handle slightly larger.
Both scissors are easy to clean.
I guess that it is a matter of opinion what scissors are found better. If you would keep both in your hand you could get a better picture of course.

Update 11/06/2013:
I am also a little disappointed in retrospect from the Gardena. I had to slide for locking stick with tape because it repeatedly
has shifted. So they always went to the locked state, and they had to unlock again.
That is why there is a star trigger again. I recommend rather then resorting to the wolf.
