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.
The item was shipped in the manufacturer’s box and just a plastic envelope. The box was crushed on one corner but luckily the bulb wasn’t damaged. I had a hard time installing the bulb into my mirror but that was due to the mirror’s design. I’m happy with the purchase.
