I think Captaincog has it above. That is what I remember Lionel saying as well, that it was a few early sets that would not work with the LC/LC+ universal remote. I don't remember if they ever said which sets or how many, but I got the impression is was a pretty small number of them.
As for the rants here, personally I read them, but they don't usually sway my purchases and I have never cancelled an order because of one. I figure that 3 or 4 folks ranting here is an extremely small percentage of the items actually sold, so a lot of them must have worked. There are also a lot of folks that buy trains, but don't participate on the OGR forum so we have no idea how their products are working or not working for them.
Also, I don't think we often hear from the folks that have good working items that have caused them no problems, like Grampstrains has posted above. I have accumulated quite a few trains over the last few years and I have had very few problems. Only one item had to go back to the factory for repair out of everything I have. Everything else was minor and I was easily able to fix these few things myself. They were a lot less trouble to fix than they would have been to re-box and ship back for repair, and a lot cheaper too.
