I try out multiple projector on the market . 1 . the Rio . 2 . the Acer k-11 3 . the Lg and the fourth one the Vivitek Qumi . the Rio be a cheap build device and with absolutely no customer service . the other all have good customer service if you need to reach they for question . or perhaps warranty issue and repair in the future . in my adventure with these projector the Qumi by Vivitek stand out far more than the other . but do carry a higher price tag . but you get what you pay for . the Rio to I be nothing more than a cheap toy . it do work but if look for a quality image and quality build with cut edge technology Qumi be the guy . the Acer be good for the money . the Lg be no match for the Qumi it be only slightly better then the Acer but much more in price . if you want a toy . go with the Rio . if you want one that be good and price moderatly then go with the Acer . the Lg be to pricey and not much better than the Acer . the Qumi be the best but most expensive and leave the second best lg in a distant 2nd . if anyone have question about detailed thing . Feel free to ask I or leave a comment .
