You get what you pay for
Is it durable? No the coupler lock spring is to weak and comes off easly and causes them to uncouple in turns ramdomly
Do I recommend them? Not really
Is it entertaing? NO!!! who wants to stop and have to randomly reach across their model train table and recouple their train
What works is they fit the gear box I use and the price is ok outside of that they're semi ok what I didn't like, spring is weak and the gap of the opening seems to large so in turn they have a tendency to uncouple especially on turns I really feel like if they could close the gap just a little and strengthen the coupler spring this wouldn't be a problem and the other complaint which is dew to the weak coupler spring when I got my package the coupler spring had cam off several of them 1 spring was in the package and luckly I had some srpings that came with the other brand when I purchased some of them so now I only have a couple that don't have the spring
