Ordered this for my 4 yr old. He loves the set, and if he were reviewing it, I expect he would give it 5 stars!
It has everything you expect from Playmobil, quality, fun, and attention to detail. However, it is quite fiddly. Eg, the wooden tree stump part in the middle just sits loosely on top. I know that sounds petty, but my son is pretty clumsy. The most irritating bit though is the meerkat food that comes with the set! Tiny tiny pieces of plastic, and many of them. It's great that a little feeder can be filled for the meerkats to "eat" from,and a food drum that can be filled with these tiny tiny pieces (complete with pouring hole in the top!) but for the time being until Tiddler is quite a bit older the toy food will be hidden safely away!
However, forgetting my irritation with the meerkat food, my son loves the set, and it is a welcome addition to the zoo.
