This large Duplo construction board (38 x 38 cm) already actually belongs to the Grundbauplatten and should not be missing in larger Duplo collections. Their field of application is diverse, even if it ultimately always comes to build something on it. Besides some advantages, there are at this Grundbauplatte unfortunately also some disadvantages. On a positive note would be that it is light and sits down on the carpet or the couch on the pad, even if the ground is not super straight. But since it's just very thin, it lacks stability. At the end of the day, the development of the children sometimes just wear on the page is not in it. We use the plate for 2 years and the small knobs have all dimples and dents. As they arose I can not say exactly, but kicked it, we are not. At least keep the blocks and on the indented nubs still properly. When times tacky liquid is spilled on it, it can be easily cleaned in the dishwasher.
I think with this record can make it right no right. Some would like to have the same size, but as thick and strong as the small Grundbauplatten. This might be too heavy and unwieldy for small children. The others call for at least a lower price for the same quality, but as long as it is bought for that price, probably unthinkable.
My personal opinion is: We have a good to mediocre building board. It is very convenient and optimal in size. Actually, you can not go far wrong here. Unfortunately, the price / performance ratio is currently not quite, but prices may indeed change at any time. I am satisfied so far and awarded 4 stars. So quite perfect, it is not just.
