I have two of these, a 130 Gallon and a 80 Gallon. The 80 gallon sits in the sun all day long and has been there for over 4 years, it still looks new. The 130 gallon does sit in the shade most of the day but I expect it will Imitate its name and last a lifetime. I use the 80 gallon in my garden, where I store all the small tools, connectors, and fertilizers. The 130 gallon I use for storing equipment for a travel trailer that I don't need in the truck when not on the road. Both of these storage boxes are very sturdy, functional, and well built. I especially like the assisted closing device, and the way it holds the door open. I am very pleased with my purchases and would definitely recommend them.
