Summary: Personal Experience A excelent poket projector. Excelent image quality and and excellent design. The contrast and colors are impressive, but the internal speaker of 1 Watt has a poor sound. A poket external speakers are recommendable. If you want to use this projector in outdoors to view films, I recommended that you purchase the Energeizer XP8000A battery, but if you want to use it as a projector in your room connected to a PC or a game console this product is great.
