I don't have enough feedback and experience but for what I use it's mostly fine so far. The only time I had feeling of it getting dumb is when I switch the comme channel and it started as a new session, acting like nothing happened before and you have to insit for it to check memory and find what was established in the previous session. I guess it's kind of feature but I would prefer to have complete memory sync unless you specifically start a blank session on purpose. But it has nothing to do with model.
