Summary: I have used at least 6 portable projectors over the past few months with not very satisfactory results compared to a full size projector because I work internationally in very poor presentation environments. I bought this one after a recent good experience with this model and I am thrilled. It is light, well-made, and exceptionally bright for a portable.
Summary: I bought this item when it first came out because of its lightness, power and flexibility. It is great. I usually use it on low power and find this plenty bright enough in most rooms and environments, in this mode it is also very quiet. The device is light enough to pick up in one hand which as a mobile trainer makes it great for me with some arthritis in my hands.
