I initially purchased the caiwei A12+ projector and gave a very good review. Alas a couple of months down the line the projector developed a bright spot on the left half of the screen. This was caused by the LCD being burnt. I contacted Caiwie and they agreed to send me a replacement LCD but I would have to pay for express shipping. I agreed and asked for additional spare parts, including an extra LCD, 2 polarizer glass filters, and a cable, all of which I paid for. One of the LCD's had a manufacturing defect, and I was sent fresnel lenses instead of polarizer glass. At which point I contacted the suppler, asking them to send me what I ordered in addition to a replacement for the defective LCD. They denied that anything was wrong, and actually tried to blame me. After replacing LCD. I now had polarizer glass burn in, yellow patch in top right corner. Polarizer glass could have corrected this. This projector is rated for 50000 hours, You will be lucky if you get 1000. Not recommended.
