Hard to open, now makes you use more

A previous iteration of this product said to use 300ml - this one now says 500ml making it quite expensive per use. Not sure if the product formulation has changed. In addition, it's also incredibly difficult to open. This version doesn't seemed to have worked as well as previous iterations.

Much cheaper elsewhere

This works a treat - but it's half this price at Tesco.

It actually worked on your very slow draining sink in bathroom. We left it overnight and washed with warm water

Worked for us!

Blocked bathroom washbasin, no idea what caused it, really! It needed longer than 30 mins but one dose worked.

excellent at unblocking drains

Have used this twice to get the shower drain flowing and its worked perfectly each time. The key to success is quantity & time. I poured half the bottle each time & left it overnight. No quick fixes here.
