To calculate the overall star rating and percentage breakdown by star, we do not 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.
Love the product and it does a great job cleaning the cups. However several of the individual pouches were missing a product tab in them so I didn't get the full quantity purchased, hence the start removed.
I purchased these tabs to get all the water spots out of the bottom of our stainless steel water bottles and tumblers! I dissolve one in hot water and shake the contents inside the water bottle. However, I wish the tabs were smaller or more to a pack, because I like to do all out stainless items at one time. So, I find myself transferring the water to the other cups. Which takes awhile and isn't always effective. But, at the same time I don't want to use all 10 tabs in one day! But, overall it is a good product and it does work.
