Have been using these in the classroom for some time to introduce students to programing for some time and was very disappointed to discover that they are no longer available.
I over all love the robot it is amazing but min is pia when it comes to the updates i hade to replace the ev3 brain because of this and it is not easy replacing a basic Linux computer but it works just fine also the cables broke but Lego replaced them i think it was because they have been sitting in a warehouse for 7 years.
I use MindStorm Lego to entertain my 5 y/0 during the COVID19 shelter in place. He is now building 40 to 50% of the robot by himself. It is rare but he can sit for 3 to 4 hours continuously building. Sometimes I get concerned because, normally, he is easily distracted... but it doesn't happen when he is building MindStorms.
I'm impressed with the entire package. I found it extremely entertaining, educational, and can be a trusted babysitter during pandemic times. Make sure your kid is old enough to understand that he MUST NOT put the pieces inside his/her mouth.
The set in itself is a great one.I really like the software. But pulling it up is very slow. It is a good set. I love the good EV3 brick. All in all it is a good set. But a little pricey though.
