I'm glad that you got a refund. Some of Lionel's recent O31 switches (not Fastrack) have issues that are documented in other Forum threads. They seem like a recipe for frustration. Some of them belong in a landfill!
Unless you're really tight on space, I would stick to a minimum of O36 for curves and switches. O36 Fastrack is what Lionel is putting in their train sets nowadays. If you already have a lot of O31 and tubular metal track, then I would look for refurbished postwar O22 switches sold by tinman3rail (see a popular auction site.) Or convert to Ross track, they also make a rock-solid O31 switch. (I wish they made them in O36!!)
I don't know how much you paid for that imported wonder. I know that new switches from Ross can seem a bit pricey. But when you think about the difficulty of installing a switch, the potential frustration from failures, derailments, bumpy operation, etc., I think spending more for good ones is worth it in the long run. My $.02.
