I'm not going to pretend I know Menards' product strategy. However, I'm pretty sure they don't intend to build products that only last a short while. I'm sure a part of their decisions are driven by price. Too high and they either will not sell or people would complain openly about it. I have several of their buildings and I bought them because they are innovative and completely different structures than what's available from others. The basic structures are built well, out of MDF and/or heavy plastics or resins. If a motor fails or an LED fails, with help from fellow Forum members like Stan2004 here, there are inexpensive technical solutions. This Nuclear facility, though not prototypical, is FUN. It lit up my train room like a disco last night. That's FUN giving it a full nuclear vibe, even though I'm not a fan of disco music. I first saw this building featured on a layout on last year's L.O.T.S. convention and I've wanted it since.
