LOL yes we do take LEGO seriously here :) GOOD on YOU for clarifying... they ARE Best-lock brand! I often post Compatible bricks here, no problems, making it very clear they are not LEGO brand :)
My son has these. He got them for Christmas from his grandparents. They are compatible with other Legos from that brand. They do not match up with his Lego Legos. So now we have 2 totes of blocks, Legos and other. They do work great though, and he does love this set. Any child would be happy to have them.
