I bought this for my first year scissors because I hoped thus cutting him easier. Immediately after unpacking flew us against the return spring ring, this seems, at least in our model to be too loose. He twisted constantly or falls in the pencil case, so that my son has this set up properly again before it can start cutting. In addition, I did not feel that this helps him back spring mechanism, since it now has to exert more pressure on pressing and thus focuses more on press than on proper cutting.
The cutting and holding properties as scissors are very good, the auxiliary mechanism for us a flop.
