Have used these for years in the paddocks - in the Florida sun. They last for about 4 - 5 years before the sun starts to break down the rim. But at this price that’s a good value. I swapped out for 50 gallon stock tanks for awhile, but those are just a pain in the ass to keep clean and every year there is at least one critter falls in and drowns. If you get these I recommend cutting a drain hole in the bottom for easy cleaning. Don’t use the plug that it comes with . . . Too hard to take out and reinstall. Instead get a rubber freeze plug or expandable wine bottle cork. Makes cleaning a snap. And don’t think putting the drain on the side is a clever idea. For some reason the horses ignore the hose (if they nibble at it, swap it for a braided washing machine one) but they like screwing with a side plug. Criminals!
