Your quality control is awful. I bought two of your chicken waterers at the same time--one from your Amazon store and one from ChickenWaterer.com. The one I bought directly from your website is what it was supposed to be (Model 2) and doesn't leak. The one I bought from Amazon was the wrong model and leaks like crazy. I had to return it. I won't be buying any more of these. It's easier to buy the food-grade buckets and nipples and make them myself. I made two chicken waterers this morning in less time than it took me to return the Amazon purchase from your store.
