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.
This bulb lasted only 5 months. I was expecting at least 1-1/2 year. Color Quality is not the same but I was aware of this and willing to keep it for the price. The original EPSON bulb lasted 3 years. My father still have the original EPSON bulb for 4 years now.
