My first order of 150 of these pads was fine and didn't leak so I ordered 2 boxes of 150 pads and they leak BAD !I have used approx 15 of them so far for a 4 1/2 lb Maltese and the floor was all wet underneath so these pads are definately not worth buying again !!!Seems they have made the blue liner thinner and cheaper so what you will get is a product that will ruin your floors. DO NOT BUY until they change back to the ones that DO work and we get what we are paying for.
