Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
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 analyzed reviews to verify trustworthiness.
I wasn't able to get this power supply into service right away as I had it for backup. Once put into service it has failed. It is still delivering 5 V but the available current has dropped to 300MA. I am not certain if this is a one-off or typical situation for this supply. It seems to be somewhat well made just judging by weight, but has failed after the return window none the less.
