Mapei BuildFix Flexible Wall & Floor Grout Black 2.5kg is rated 4.7 out of 5 by 24.
Rated 4 out of 5 by from good alrounder One of the better grouts I use, good value, holds up well against water and grease in the areas I mainly use it for, goes off pretty quick which is mostly a bonus for any repairs, would be good if Screwfix did bigger size option

Rated 5 out of 5 by from Excellent Product The product was good and easy to use it was a reasonable price and collecting it from the store could not have been easier. The only down side is that I would have preferred a smaller bag

Rated 4 out of 5 by from Pleasantly suprised I normally struggle with grouts but this was simple following the directions.A bit like plaster products.Much easier to rework when dried the right amount.Stir during application.First use so only rated good on reliability.
