Query: Do not be fooled! Looks like lego, but isn't as good

My son recieved this set as a birthday gift, and was very excited about it. He loves legos and transformers, so what could be better than combining the two? How about a toy that stays together? We put this toy together and found that the pieces do not fit into each other as well as legos do, and the slightest jar to them will send the entire thing into peices. It was very frustrating. You can't glue them together, either, if you want ot be able to "transform" it into robot mode.Very Disappointing.
