If you don't want to bother spending time programming a Micro SD card for your Raspberry Pi B+, this is what you're looking for.

On an ample 4GB of SanDisk goodness, this card can be plugged into a Raspberry Pi B+, and will go straight to the Bartendro UI on boot. 

Make sure you're using it with a compatible WiFi Dongle if you're trying to access the UI with wireless devices.
