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.
I gave this to my wife as a Christmas stocking stuffer. She hates it. The focal length is very short, so you really have to get close to get in focus. And then the lights are so bright that it is hard to see. It's blinding! I may return it if the shipping is reasonable enough to make it worthwhile to do so.
