I've texted you for understanding the problem, but not getting reply. Not sure what you expect for the projector, the original price just 89 USD, it may not having excellent performance, but it works. Very sorry about your upset, but seems there nothing what i could do -- 完成交易後取貨後還傳訊息說如果還有投影機也請賣給他 然後留個1星評價也不知道是遇到什麼狀況也不回訊息 只好調整評價
