Before I became a parent, I didn't understand Lego. Now I love Lego. My kids love Lego. We'll spend an hour at the Lego store every few months filling up a bucket of parts and spend hours piecing different inventions together at home in quiet focused play.
The only complaint I have about Lego is the price. The kits are very expensive, even the basic kits that don't feature licensed superheroes or star wars. A little police truck or car is $20. My understanding is that the expense comes from the precision with which the bricks must me manufactured, but $160 for a robotics kit is still prohibitively expensive for many people.
That said, this kit does appear awesome.
