this projector work fine for two month and seem like a great buy . then it stop work . it will work from ten to thirty minute and then the screen go black . since it last more than 30 day , I can not return it for a refund . the seller do not respond to email . theoretically it have a one-year warranty , but what good be that ? the manufacturer be in China ! the seller be in Texas but do not respond . another thing : once you buy this thing , where be you go to get replacement bulb for the projector ? you do not see they on sale at Amazon , do you ? consider buy a use projector , that originally have a much higher price , on eBay . that be what I 'll do now . but watch out for the high price of replacement bulb in that situation , too .
