We've used this type of waterer for several years now. Our first one rusted out in a couple seasons, I think mainly due to the fact that we never bothered to clean it out very well. With our second one, I usually scrub out the bottom every couple months, and has held up about 3 years now without rusting.
I like the 2 gallon capacity -- doesn't need to be refilled as often as the other plastic 1 gallon waterer we use in the summers. It is easy to carry full of water by using the internal handle (i.e. the one in the "tank", with the top off). When I get out to the coop after refilling, I put top on there and then hang it back up.
To hang by the outside handle (i.e. the one on the top), it needs to be modified in some way to keep it from sliding to one side or the other and spilling all the water out. We did this by lashing the handle with some thick cord, leaving a gap in the middle for the hanging hook. It now hangs securely from the middle of that outer handle, with no room for the hook to slide off to either side.
