Yep, they're solid. The container I got was exactly as described (wind and water tight). No weird rust holes or busted door seals. Definitely a much safer bet than the sketchy guys selling them on Facebook marketplace.

Man, I saw a video where a guy used one to find his wedding ring in a drain pipe. Those things really do save the day.

Watched my buddy last winter spend a whole weekend with a caulk gun and weather stripping, trying to keep his apartment warm. His power still went out for two days because a transformer blew down the street. He did everything right on his end, but the bigger system failed him. That's the whole problem, we shouldn't have to choose between personal fixes and working infrastructure. Both matter, and it's crazy we have to argue for basic reliability.
