Good but a bit easy!
My not-quite-4 month old border collie cracked it in 20 mins (5 mins each section, doing just 1 section at a time to begin with). However, she still loves it and will ask to play it most evenings. When I get it out, she jumps around with excitement and enthusiasm!
One problem is she that has learned to pull the pegs (that hold the game in place) out, and as they are a size that she could choke on, it's another game all over again whilst I try to get them out of her mouth. It would be much better if the pegs screwed into place.
In the illustration the drawer and the lids look wooden - but they aren't, they're plastic which is disappointing as they don't cope well with enthusiastic chewing.
