its pretty horrible to work with, grouted 16m2 bathroom walls today with mapei and it was a chore , its okay for floors and small wall areas or large format porcs ..I used to use Dunlop flexi grout, or ordinary dunlop grout with flexi add, but neither gives as good results as bal, I've spotted a store who does mapei grout and might have to give it a try...Hmm anyone used to mapei?
