I was skeptical at first, I had already ordered another Beamer and return mail sent him back, because you had the feeling to sit next to a hair dryer ... But as I have the Acer P1173 unpacked and connected, I was thrilled from the first moment ! The connection with iPad and MacBook Pro is easy, as boxing I have the Bose SoundLink Mini (I can only recommend) and even the home cinema feeling is perfect. I project the image of a white Raufaserwand and the projector delivers a great picture. He is extremely quiet, especially in the Eco mode, even if it is in the direct vicinity of the viewer. And with the price-performance ratio, I can pronounce an absolute buy recommendation!
