Have always used Rubbermaid Stock Tank. Thought I would try something different. While testing before using it leak at the drain plug. I really tightened good and the water stopped leaking. OK, I can deal with that. So now that I was done testing, I went to unscrew the drain plug to drain the water. The plug would not unscrew, instead the whole piece that it screws in unscrewed for what it was attached to and separated. Yeah, it drained You would need to clamp the part on the inside of the tank to just remove the drain plug. Not acceptable. Took it back and got the Rubbermaid.

The rubbery material withstands jerk horses better than Rubbermaid and they are FAR easier to clean!

Very disappointed with our new Tuff Stuff 110-gal Stock Tank. We have one in another pasture that meets our needs and wanted to replace an older Brute that began to leak via a crack. Our 2-year-old Tuff Stuff is great, easy to clean, walls are relatively stiff so we can dump a < half full tank. Our new one is EXTREMELY flimsy and seems to bulge out when full. Dumping is not easy due to being flimsy. It reminds me of the Rubber Vase in "You've Got Mail". "Is it porcelain? Rubber."

Tank is well made, should last for years.
