Amazon calculates a product’s star ratings using a machine learned model instead of a raw data average. The machine learned model takes into account factors including: the age of a review, helpfulness votes by customers and whether the reviews are from verified purchases.
I don't know how long it will last but I don't expect quality miracles from such a low priced product. More importantly, I tried it out straight away on two of our three cats and it works a treat!! Both loved it and started purring straight away, and I got a ton of hair out of them in less than two minutes. One of them is a very old, long-haired boy and I was getting worried that the grooming might get too much for him and his stomach. This will definitely reduce the hairballs. Really happy, will order again when the time for a replacement comes. And I loved the cute thankyou card :)
My kelpie x is in love with this. As soon as she sees it she comes running. Its like a massage from her while removing all her loose hair. It all sticks to the glove and comes off easily when im finished. Even my kids can use it and its a great quality. Thanks
