    I have experienced many projectors before and this one is the first one for me to own for myself and I must say, it is one of the best for the price paid. Would’ve been a 5/5 except for the fact that when you attach external speakers, it doesn’t automatically disable the internal ones, but apart from that, highly recommended for first time buyers.
