I have been using this product to conduct meetings in my work of place and I can share with you that this product is one of the reasons that I am recommended every time I give a report. Am not trying to make thing up, am just giving you guys the fact. And one reason that I do get commended is due to the viewing and the length it can go. Please, not all projectors are same. Am writing from experience and I know the difference. No matter what distance I place this product (projector) the images or files not only gets bigger but clearer. This product has been good luck to me from the day I bought it and I don’t regret it.
