Review on 3Stone Upgraded Mini Projector: Portable LCD Video Projector with 1080P Support, Built-in Speakers, and Multi-Device Compatibility - Your Perfect Home Theater Solution! by Ron Coleman

I am very impressed with this projector, it is a great product and good value for money. Met my needs well. Haven't used it indoors yet so not sure how well the sound will play in an enclosed space. Outside, however, I needed to hook up an AUX port to a portable speaker. I was happy to see that the device comes with an AUX output. The Projectes screen size is HUGE! I used a medium sized gray tarp that I use as a footprint under my family tent. I'd be lying if I gave an approximate tarp size because I honestly don't know, but it's not the smallest tarp size I know of. Since the king's white sheet was too small for the projected size, I didn't figure out how to scale down the projection, but in my haste I couldn't easily see the button that did it. I'll refer to the manual next time if I get it done in time before planning to use it next time :-)
