I’m really impressed with this $400 portable projector

The Lumi Max is a $400 portable projector that weighs just over 4 pounds and runs Google TV with access to 10,000+ apps. Key features include autofocus, obstacle avoidance that detects objects on walls, 40-120 inch display with 1080p resolution and 4K compatibility, dual 5W speakers with Dolby Audio support, and a compact vertical design suitable for small spaces and travel.
