Superb!

These DIY spider robot STEM toys are amazing! The 16 year old grandsons love them! I love to see them doing something other than looking at their phones or playing video games! These are large and fun. They are fairly sturdy and easy enough to assemble! There is a video on YouTube that explains it all really well, making it so much easier to get these built. THEN after they are built the boys had so much fun running around after their sisters making them scream. Lots of memories and laughter. It does require an AA battery which is not included. This is motorized and has movable parts.
