I want a cheap led movie projector . I first order the Optoma pt100 , but there be a number of problem : color be not accurate , would not stay in focus , etc. . the Acer k11 be excellent : the color be accurate , the picture be bright enough . I be hesitant to order it because of reviewer who find the fan noisy . I do not think fan noise be excessive , especially when the projector be set in `` video '' mode . this projector do everything it claim to do . with a power draw of only 83 watt and a 30 000 hour bulb light , it be a economical device . its compact size make it portable . I also buy a $ 10.00 tripod to set it on , a 80 inch Epson Duet screen , and a JVC thba1 soundbar . for a total of $ 630.00 $ , I get a nice portable system .
