Works alright, it gets a bit slow till you open the factory and unions, then it speed-up, but when you start science it becomes slow again till you work on your theories multipliers. I know it's still being worked but the lab really needs something there, cause using theories to upgrade the raw gains or the gains multiplier resets the stacking gain of theories making it really bad to go past 50's on each depending on the level you are there, cause it would make it take away too much time to get the necessary currency.
