Yes, I have. I think it's about the equal of Atlas code 83 flex track and may even come from the same manufacturer. It seems a little more flexble to that Atlas track, which is both bad and good. Easier to form a curve but you need watch for kinks a little more that with Atlas track. I'm convinced that good trackwork is about 90% skill and 10 % material so I'd get it if it was a good price.
