You might have had numerous encounters with the maasai people while on safaris but be assured that these might not be the authentic maasai people. Even if they were the real maasais, they might have been putting up a show for you as they receive tourists on a daily hourly basis.
In this tour you get to interact with the authentic maasai's day to day life away far away from the safaris and the National parks.
This becomes an experience more than a tour as you do the things that the masai do on a daily basis. You get to appreciate your conventional comfortable life more. From cooking ugali in a manyatta, beadwork, lighting a fire traditionally using sticks and cow dung, milking a goat, dancing, singing and jumping with the Maasai people, you get to do them all.
