Mapei BuildFix Flexible Wall & Floor Grout Black 2.5kg is rated 4.7 out of 5 by 27.
Rated 5 out of 5 by from Grout Colour The grout is not black it is dark grey at best, not even charcoal. It would be more realistic to call it charcoal certainly not black it is missleading. That said it mixes, applies and finished off well, can't fault the product or it's usage only the colour description realy. Should have read the reviews first LOL

Rated 5 out of 5 by from Good finishing touch Used with some variable tone black floor tiles, grout is not a true black when seen against these tiles but a very dark grey, almost black which set them off perfectly.

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 5 out of 5 by from Excellent product As an external grout, this product is unbeatable. It;s easy to mix, easy to apply and cleans up with very little effort. I wouldn't hesitate to recommend this grout to anyone.
