This product image shows that the bag measures 14.5 x 20.3 cm, each ball is 1.27 cm in diameter. The bag I received is closer to 2" x 3.5", it doesn't even have a 1 1/2" ball. Also, the photos show all the balls being the same size. The balls appeared to be two sizes : 5 of them were about 3/8" diameter and the rest about 1/4" These are just my first impressions of the product.I was concerned about the misinformation in the ad but I am giving it 2 stars because I am pretty sure the balls will work fine for my shrimp at least I went with this product because it looked like a good deal but I don't like being lied to.
