I bought 2 12 packs for testing, and I've been reasonably happy with them. I don't like how wide they are, and rank them behind FVM and BLMA in that regard. All 24 axles were in gauge and run through my trackwork without issue - I scattered the cars through the layout and over 3 op sessions they've been pushed, pulled, kicked and shoved with a lot of forces in all directions. I put looks pretty high on my scale, but if it weren't for that I would probably be happy with an entire fleet equipped with them.
