I purchased the Verizon 4G LTE version and I am thoroughly impressed with this smart projector. It has surpassed my expectations in every way conceivable. The display quality is superb at 100 or 200 lumens. Movies and PowerPoint presentations looks amazing even at 100+ inches in a moderately dim room. I am able to connect my surface Pro 3, note 4 and flash drive with no issues. The remote control function works flawlessly. This is a great product; I highly recommend it even at the $550 price point.
