I guess your mileage may vary. I've had 2 pretty much from day one without problems. I'd suspect either poor components or manufacturing. The design IMO other than the charger is pretty solid.
Chuck I would make sure you politely emphasize how many you've returned. While they don't charge you to fix them typically, they should also take care of your shipping being that you've had to send them back so many times. Sometimes the squeaky wheel gets the grease.
Hope you get it straightened out. Personally I'd rather use a remote over a smart device any day to operate engines. You may find it different.
Did you send in the Base(s)? I had to send all of them back for a charging update. I've only charged in a charge only base, but Lionel person talked me into having them all updated for charging issues.
I guess the first one I bought had to be sent in for the silver dot so that sort of doesn't count.
Actually I also had to send in the charge only base too because it went dead and took out the fuse in the wall wart it runs on. In fact I blew two wall warts thinking that it was the wart, and plugged in the second. Then it dawned on me not to try another and fix the two that had their fuses blown.
Marty, I think they have my name on a list . Once they said "which one is this". I said they all look alike and there is no serial number on them. I promised to number them and keep records. I don't know why it mattered since they fixed anything I sent in.
The faults I had were all bases charging, charging base dead, Cab2 back light out, Cab2 display messed up, Cab2 button row dead, Cab2 feedback non existent, and now Cab2 won't stay on.
I do not want to rely on a smart controller. I like buttons and knobs. I like to walk around and not have to stare at the controller to see where to touch, I'd rather watch the trains. I am set up for i-stuff, but only because it was a challenge and a possible backup. That all works well...the layout thing in the iPad could be a little easier to draw and more curve diameter choices. I would also like to be able to draw the layout like with something like RRTrack or AnyRail and load it into the iPad. Maybe some day, eh?
Thanks for the interest.
