I got this when I was elo 200 I played with it and got up to elo 1000 but I soon relaized that was cheating so I stopped using it and I had noticed I had gotten much better and into 600 elo and whenever I had a problem I could use it to teach me. And as of late the reason why this is only 4 stars is because it stopped working in matches it still works just fine but I get an alert saying chess.com says you may use this extension after the game.
