Control your BB-8 Droid with this Sphero Force Band on an available Bluetooth Smart connection. Covered in sensors, the band detects wrist and arm movement and cues BB-8 accordingly, letting you eschew the smartphone app for more Jedi-like control movements. The Sphero Force Band fits easily on your wrist via an adjustable fastener.
I bought this for my 12 year old daughter to go with her BB8. It works perfectly. It also gives you the ability to collect Star Wars Holocrons even when you're not using it to control the BB8.
