My original order arrived damaged. It was packaged in a plastic envelope so it was dented and torn. HOWEVER, the seller sent me a replacement for free, so I am very grateful. This works great for my grandson but I thought it was "VIEWMASTER" but it isn't. Actually I'm not sure if I can find more compatible coils. The rest of the space coils are good. I personally would prefer a real VIEWMASTER. Lesson learned 👍🏼
