This is the 2nd order received in the past few weeks and would definitely recommend. The tiles we bought were more than double the price in local tile shops! Delivery was quick and received on date scheduled.

Have used other silicones in the past with varying results of disappointment. This was a great product, does exactly what it says on the tin and our bath is now completely watertight - fab!
