Example Input: The fine sands sticks to my cat's paws and she will trace it all over the floor. That causes dusts and when it gets wet,,,, even worse! It starts smelling funky as soon as I replace with the new sand. ( it is more a sand smell, not my cat's) I still get the regular Double Duty one.
Example Output: 2

Example Input: Selected one case and was sent another one. Contacted customer service and the rep argued with me refused to send the correct one or refund my money. Will NEVER ORDER FROM HERE AGAIN RUDE!!!!
Example Output: 1

Example Input: The only thing I would change is the size of the mesh filter which has a very small capacity. I have to fill it about three times and then it loses enough heat I have to nuke it because I add half and half. But, I really like this unit a lot.
