evidently you do not have a level 7 city or you would see that it does NOT work...you get no extra lab chance to use with gems and stamina...so not only is it not free as the description says, it does NOT even work. to simplify this so people understand...you have the same number of chances to do the lab before and after taking the level 7 city.
