I first saw a projector like this quite recently being used to give a talk . It looked like an Apeman but was another make. I checked it out and forgot it instantly because of the price. However, when a canny Scot says they use a mini projector in their camper my ears pricked up. I checked out the Apeman website and studied the beast and together using the discount offered I bought and I am not disappointed. I am amazed what this tiny elegant object can do. Right here goes. Sound is 50% of a film isn't it?. Well the sound is crisp and bright, quite amazing for it's size . I put on my Sennheiser professional headphones to check the quality, now that was good. What about vision. It's not 4k it's 480 p! But feed in 750p from say YouTube via your phone of you favourite music. I was away . The projector was propped on the back of the sofa and aimed a darkish corner of the room away from the glare of a brightest afternoon and the hour or so of charged went in a flash. The colour was surprisingly good, the brightness would have been better using a small projector screen and a dimly lit room. Bingo, just what I needed to wile away darker autumn evenings in the camper with my favourite drink in hand.
