To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
We were satisfied when receiving the projector. It wasn't amazing but it did the job for a budget projector. 2 months after owning it a white spot appeared on the display which we thought initially was just dust or a mark on the lens. That yellow spot has now turned into 6 yellow spots and after doing some googling is very difficult to fix making our projector now obsolete. Bad value - even for the price you would expect the item to last longer than 3 months. We attempted to contact the seller also in regards to a refund and never heard back.
No matter how you try, you will never be able to get rid of the blur. You will have to deal with the top or the bottom of your viewing experience being blurred out. At best, you can get to make the bottom and top to be half way blurred. So using such things as a computer, for web pages, terrible. A movie with words at the bottom or top, you're screwed. Etc., etc. It's just not nit picking. I mean it's really blurred bad. It actually pulls your attention to it from how bad it is. If you're like me, and you want to enjoy the viewing experience of a large screen as much as it is large. This is a bad one to pick up on.
