Bests & Worsts Reviews from Amazon

I bought this projector for my Halloween projections, which I display in the window overlooking our neighborhood which is VERY into Halloween. I set up the projector according to instructions, began projecting and within 5 minutes a dark spot appeared in the center and spread quickly to block out everything. Instructions said this can happen if the bulb overheats, and to turn it off for 3 hours then try again. Well 3 hours later is about 3 hours too late, but I did it anyway and the same thing happened. Within 5 minutes. I reached out to the manufacturer as instructed in the manual and received no reply. So I returned the product for a refund. Would NOT recommend this product or manufacturer.
