Bests & Worsts Reviews from Amazon

These are truly quality building pieces. My 4 1/2 y.o. grandson and I spent several hours building with these. He loved what we built and wanted to make more. My only criticism is that there are not packs of some of the more needed pieces. After we built a few vehicles, my grandson didn't want to dismantle the ones we made. We had MANY strip pieces left to build more but we were out of block pieces and screws. I would like to be able to buy packs of screws and blocks so I could use ALL the pieces included. I looked everywhere to buy more parts only to find there are only two pack to be had...the one I bought with 163 pieces or one with 101 pieces. Company needs to either include more block pieces and screws or sell them in packs alone.
