I use them. They are solved for $2/$5 nl 6 max cash BUT gto is not necessarily the most ev play especially if you are playing players who are NOT playing close to gto.
If you use these, you will probably be looser and more aggressive preflop than many players so you will find you will take down a lot more pots preflop out of position and find yourself badly dominated in some on the flop.
Follow them but only start deviating when you are sure an opponent is making mistakes and what those mistakes are.
