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 would highly recommend the dancer rainbow for cat lovers. It has become my cats favourite toy. It’s is well made, a very flexible handle, long enough for my cats to wrap around themselves, light enough for them to drag around. Have saved the item for when I need a new one.
