BB-8 Droid by Sphero

$150

amazon.com

Star Wars: Episode VII-The Force Awakenswon't be released in theatres until Dec. 18, but Disney has been promoting their Star Wars franchise toys and gadgets that have been on sale since early September.

Experts expect Star Wars merchandise to generate $3 billion in sales this year. One particular gadget has been sold out for over a month, but might be available to purchase for the gift-giving holidays-if the stars are aligned.

The BB-8 Droid manufactured by Sphero is certainly one of the biggest hits in the Star Wars line-up and a classic toy for adults as well as their children. The gadget is controlled by a free app on your smartphone or tablet and has impressively authentic movements and expressions. It is designed to recognize and react to its owner's voice. In true Star Wars fashion, the gadget can create and project augmented reality videos which Sphero labels "holographic." As you and BB-8 explore the galaxy (or backyard) together, it quickly becomes evident that the Droid is capable of displaying a mind of its own. This gadget is one of a growing number that learns and evolves as you play with it.

At 4-1/2 inches tall and cute as a button, BB-8 is the R2D2 of today. This spherical droid is expected to be one of the most charismatic characters introduced in Episode VII. He's a rolling ball (actually two balls) of fun. You'll just have to wait to play though. Amazon quoted a 2-3 month wait soon after the device became available.

On a side note, Sphero is a toy company that has been marketing their particular brand of robotic gadgets since 2011. They became one of the first members of Disney's Techstars program for startups, earning them a small investment as well as the kind of marketing and promotion that Disney has mastered over many decades.
