Love my jurassic , I have never had a problem with trex, but it shouldn't be hard to figure out, I read once the teeth were bend slightly and that's what cause his problem with him not picking the ball up. The scoop problem has happened to me , my switch was still good , I just had to adjust the wire on it so the ball depressed it more. As far all the drained ball and flipper, I wish I knew as mine does that sometimes too . That price is a steal in my neck of the woods . Even with the issues you talk about it would have been 23-2500 firm. When I bought mine I had 4 different switches not working, it was a totally different game when I found the switches and fixed them !
