Hand replayer

Hey everyone, I just wanted to get everyone's opinion about the hand replayer (I'm using the hand replayer on Pokerschoolonline) and how's the best way to use it to learn from the hands you just played? Right now I've just been replaying them and trying to find bluffs and any hand setups I missed on the hands I folded or lost. Any advice y'all can give is greatly appreciated as always

I prefer to watch the players at the table as I play low stacks and often their plays do not make sense.
But in a tournament is a great way to know your mistakes, most of the good Brazilian players do this.
