HG Duo Unblocker Extremely Powerful by HG

The media could not be loaded. Bought as it had a money back garentee .I pre cleaned the S pipe before purchase and I couldn't get everything out from the outlet pipe that connects to the path for drainage.It stunk and it was vile.I didn't pour the first dose down the plug hole.. as that was not blocked. I did it down the issue pipe. Thinking about gravity and how it would not be able to work without pressure that is not mentioned in the instructionsLeft for 6 hours.Initially it looked to have worked but then the sink backed up again. So the second dose went down the plug. I measured on ml how much water would need to be added for it to reach the down pipe blockage. So it wasn't sat where it wasn't needed.Left it for 3 hour's.Drained it and its now free from blockage

Effective for clearing shower drain blockages. May need to use twice though. Good value

Purchased this after 2 other failed attempts at unclogging my bathroom sink. Left the product to work overnight and was happy to see it worked. Highly recommend!

I am happy with the product

I hoped that being a 'two bottle' product, where once mixed, the two reagents are more effective than the various 'one shot' products out there, this would clear a particularly slow draining wash basin.Despite following the instructions 'to the letter', what is described as an "Extremely Powerful" unblocker failed to improve the extremely slow flow at all.I'm just please I only bought one package and didn't waste money on two or three.

It literally does what is says, clears shower and sinks drains, can’t recommend it more highly

This product worked for ts, this one has cleared the blockage and the drain is running away normally. I inadvertantly followed the"kitchen" instructions not the "bathroom" ones as I should have,and I followed it up with the plunger to maximise its chances and it is working better than it has done for ages.
