This has apparently been out a while I think - it matches my MTH UP Passenger set to a "T" so I bought one for the incredible price of $148! And being in line with most Chinese garbage one coupler is defective and thanks to my quick action my Challenger narrowly avoided smashing into the observation car when the coupler let go! I don't see anything obvious but 2-3 times around the layout and it lets go. Great stuff! Gotta love it!
Other than that it is a nice looking car! LOL!
