Sphero 2.0 comes to us from the same people that created Ollie and we fell head over heels in love with him so we were excited to get our grubby paws on the original product. Sphero 2.0 is a tough polycarbonate ball that is propelled by an electric motor and controlled via Bluetooth from an app on your smartphone or tablet, it has an inbuilt LED light for playing in low light and can travel up to speeds of 4.5mph.
