Query: QUALITY FOR PRICE

I HAVE BEEN PURCHASING THIS ITEM FROM AMAZON FOR AWHILE NOW, BUT LATELY I HAVE NOTICED THAT THE QUALITY EACH TIME I PURCHASE THESE TRAINING PADS HAS BECOME THINNER AND HOLDS LESS DOGGIE WETNESS. I HAVE TO CHANGE IT MUCH MORE OFTEN, SO I WISH TO CHANGE A FEEDBACK I LEFT ONCE BEFORE ABOUT HOW GREAT THIS PRODUCT IS FOR THE PRICE. I AM VERY DISAPPOINTED IN THIS PRODUCT BECAUSE IT JUST DOESN'T DO WHAT IT USED TO DO. AND NOW I WON'T PURCHASE IT AGAIN BECAUSE THE QUALITY OF THIS PRODUCT NO LONGER WARRANTS SUCH A HIGH PRICE FOR ONLY 16 PADS.5/2/11 WHILE I DO LIKE THESE, THEY SEEM TO HAVE BEEN SKIMPIER AS THE TIME HAS PASSED SINCE MY FIRST REVIEW. I FIND THE "TOP PAW" PADS SOLD AT PETSMART MUCH BETTER BOTH IN PRICE AND IN DURABILITY; THEY ARE MADE MUCH BETTER -- QUILTED AND STEADY WITH STICKIES ON ALL 4 CORNERS THAT YOU HAVE A CHOICE OF USING TO ANCHOR THE PAD DOWN. STICKINESS REMOVES INSTANTLY WHEN YOU REMOVE THE PAD.
