No Nonsense Sanitary Silicone Sealant Manhattan Grey 310ml is rated 4.5 out of 5 by 16.
Rated 4 out of 5 by from It's not bad Seems to be ok, used it for the sanitarywear and skirting after vinyl tiles. I don't do much siliconing but easy enough to handle and price is definetly good.

Rated 5 out of 5 by from Great value product I bought this to seal a clients grey tiles to black worktop, it proved to be a better colour finish than the standard white. Great feedback from client who was well pleased.

Rated 1 out of 5 by from Avoid!!!!! I installed a bathroom for one of my good friends last October. I used this cheap alternative as I couldn't get hold of any Dow Corning or Mapei in grey. Unfortunately I have paid the ultimate price for going cheap as I got a phone call last week from them saying they have a damp patch on their recently renovated kitchen ceiling. Naturally I got round there quickly as I thought it was something I had done. Upon inspection half of the silicone seal around the shower tray had come away at different points after just 10 months..... Avoid at all costs stick with Dow Corning or Mapei this really doesn't compare...

Rated 4 out of 5 by from Top product Once again Screwfix has been able to deliver a top product linked to excellent customer service. The colleague we spoke to at the Wigan store was very helpful and had great product knowledge. I used the sealant on return home and was able to achieve a perfect result.

Rated 4 out of 5 by from Good Product Have used No Nonsense silicone many times all with good results. The choice of colours lets you move away from the regular white. A little "thinner" than the proprietory brands but this makes it easier to work with, especially when taping.
