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.
Good and affordable product. I bought it to inflate soccer balls and it does it perfectly. It comes with a metal needle for sport balls and a plastic one for beach balls and the like. I haven't tried it on my bicycle but I do not think it would work very well. It does not have the extension needed and the pressure is probably too much.
However, if you want this for balls, this is a great choice.
