I have used cobalt digitalis on my last four layouts. ( re used ) I like the idea behind them, the easy connections, the positive throw, the ease of installation, and the simple programming.
I don't like the unexplained loss of address which can and has on numerous occasions occured following a short. I manage to pre test my layout befor a show, dismantle it, transport it, set it up and, wham, it is the norm for one or more to have failed.
This has occurred this weekend at a show and has been very frustrating, I managed to remove and swap one motor,but a second is just dead.
On a positive note, the frequent over stressing of the cogs that resulted in a continual ratcheting of the Motor is easily cured with the replacement of a cog that comes in the post from Australia after a week or so, which you fit yourself.
My next layout will have solenoids and a CDU.
