Very positively: The processing is very stable, it also keeps the somewhat gross motor shepherd of my parents was good. In addition, it can be, since it's made of plastic, wash well. Our wooden toys were mostly eingesaut quickly chewed and discolored ugly.
Our dogs have to, for example, very different techniques to get to the treat, which is interesting to watch for us again and again. Moreover, it also fulfills the purpose to occupy my Hundeopi because he played 20 minutes after ca (we have plus the Dog Activity Roulette and fill both alternately or each only half) is really done and first inserts a little break.
Only the small yellow lever were chewing something while playing, they are fortunately but so stable that they crack or the like is not the same.
Overall, highly recommended and super value for money
