Drain Blast Unblocker is rated 3.2 out of 5 by 29.
Rated 3 out of 5 by from Astonishing! I haven't yet bought one of these, so it's astonishing that I shouold have the balls to write a review. But the main reason is to see whether the system picks up the fact that when I say Amazing! Wonderful! Magnificent Value!, I do so without a shred of evidence or justification

Rated 1 out of 5 by from Utter Garbage Do Not Buy. Have used many of these over the years, and the rest have been ok. On using this item on an innocent blocked sink, i got a very unsatisfying power shower of sink" water on completion of my second back stroke, most of the water was jettisoned out around the handle under significant pressure, soaking me, the mirror the wall and not forgetting the floor. So there you have it ! Toolstation get the slightly better type in stock and charge us a quid more!, and we, your valued customers will be happy, Cheers.

Rated 1 out of 5 by from Rubbish Garbage. Worked for one "blast", then the seal went so water just ran straight out. No way to open to investigate a fix. At less than £3, not even worth the fuel to return it. Maybe I just got unlucky, but would not recommend.

Rated 1 out of 5 by from Worse than a bag of farts Brought on the basis of hmm might help the with my blocked sink and it's cheap. What total and utter rubbish! You have to try and fill it upside down, which is tricky enough in the sink given it's too long to fit under the tap, unfortunately as it's not water tight all the water just comes out the other end! If you do manage to find a way to fill it, stop water coming out either end, get it to the sink/plughole, cover the overflow pipe and push water out of it before it all just trickles out anyway then I assume you must be some sort of ninja. Also special shoutout for the helpful 5 start reviews that say they haven't used it yet, really helpful...

Rated 1 out of 5 by from Worse than useless I read good reviews about this and this type of product. Long story short: water has to be poured in at the "out" end whilst it trickles out where the push pipe enters the other end. It's like some "It's a Knockout" game on a much smaller scale. Felt I ought to be dressed in a huge foam Mario Brothers costume as I raced to get enough water in to try the pump. Once I had, I had to put my finger over the end , quickly try to smother the plug hole ( having unscrewed the push type plug), cover the overflow and push the piddling amount of water left in the tube into the plug hole. " You get what you pay for Ha Ha Ha! " I hear Stuart Hall scream as they drag him back to his cell.

Rated 5 out of 5 by from sink, shower blockage etc I have not had to use this yet but having had one previously I do know that they work . vinegar and bicarbonate of soda does a good job of clearing a drain of grease debris build up but this pump should give a good suction where a blockage is remaining.
