I do all my RCs with expectations that something could be off, but the hand-related ones tend to fail quite a bit, whereas the nose-plug hasn't failed me once.
I'm also gonna add that dream control can fail, so it's a bit more risky to try using your own original RCs than to use the ones that have been known to work well.
