Thank you for viewing. LEGO SPIKE Prime Basic Set + Expansion Set Used for about 2 years in a robotics class. The basic set has all the parts. The expansion set is missing only one part. The basic set box has traces of a sticker on the side where a name sticker was attached. The expansion set box is not included, so it will be packed in two bags. It takes nearly a full day to fully charge the main unit. This is not a defect, but seems to be the way it is from the beginning. Please understand.
