Up for auction is a Brand New Factory Sealed Roku Express 3900R Streaming Box. I have 2 of these 3900R models available but they are offered herein separately and sold individually. This highly versatile HD streaming device runs ROKU OS which is fully supported by Roku and continuously updated. Per ROKU, the 3900R is a full 5X more powerful than previous ROKU Express models and offers playback in 720p or 1080p high-definition depending on your display's capabilities. These devices are plug and play easy to install and this model even includes an AC power adapter, not just a USB power cable which many other models lack!
