Summary: The projector produces a very descent image quality even in daylight conditions. I used it mostly for viewing videos and in full screen the image is very sharp. It's also extremely small and I can carry it around in my laptop bag. The only drawbacks are the noise and the length of the VGA cable. 2 are related. Because the cable is so short you have to keep the projector close to you and thus the noise problem becomes even more apparent.
Summary: I am quite pleased with the size of the projector (I did want something small) and the quality of the picture is great. Everything is working right out of the box and have had only one problem. According to the PDF manual it supports a variety of MPEG video formats. When I use my thumb drive to plug in my video demo the only one that seems to work is the iPod H264 video format which is much too small. I have tried: MPEG-4HD, WMV, DV, and some others, but no joy.
Summary: this is a great little projector i use it for everything and the picture is awsome. but the only bad thing is it doesnt have an audio output so when im playin my xbox on it you cant hook it up to bigger speakers then the one thats on the projector.
Summary: I love my new mini projector. It has great picture quality and is small and convenient for travel. My only complaint is the lousy internal speaker. I really wish it had an audio jack so I could hook up my external speakers.
Summary: This projector delivers excellent performance and projects more than 100 inch easily withouth any compromise in picture quality, really portable,even fits in pocket. It works in 50% dark room and when the room is completely dark, the picture quality is so bright, gives the theatre experience. The only drawback is, one cannot plugin woofer/speaker to this Projector.
Summary: My mother-in-law needed a portable projector for a string of upcoming presentations she was going to be doing. The requirements were simple: it needed to be portable, it needed to be affordable, and it needed to be simple. This little guy is all that and more packed into an incredibly small package. The image it throws is crystal clear, and it's plenty bright to throw a 6' image up on a moderately dim room.
Summary: I have only had the projector for a month, but so far I am very satisfied with it. I only use it to show photos or short video clips to family and friends and I have not been disappointed with anything so far.
Summary: Acer k11 is just what I needed, and what I was expecting for. It has a good quality for its price. its not for a big and bright place. I knew its con with sound, very weak speaker. better with hdmi connnection. better with a really dark room. preferible to use with a battery system (ups). from 1 to 5 my calification is 4. although I knew its cons. I recommended, excelente price and quality.
