Drain Blast Unblocker is rated 3.5 out of 5 by 39.
Rated 4 out of 5 by from Easy to use if you figure out how I gave 4 (Good rating) as although it hasn't (yet) been able to dislodge whatever is making my shower drain extremely slow, it is easy to use and can tell it does apply a good amount of pressure and would be good for unblocking less hardy blockages. Reading reviews of people complaining about it being useless, being unable to fill with water before using. The best way to use it is to have a large bucket of water to suck into the tube, then immediately place it over the sink and push back down. Water can splash around a bit (especially when you're sucking the water up from the bucket), so be conscious of this. Water will flow out between sucking in from bucket to covering the drain, so just need to be quick with the action, which is why I suggest a large bucket of water so you can do it a number of times.

Rated 4 out of 5 by from Does what it should. It works OK, it was to replace one that accidentally got thrown away, and that on seemed to be more powerful, but it works OK.

Rated 4 out of 5 by from Fab Blocked kitchen pipes. Tried lots of treatments but this is the thing that worked. Took a while to figure out how to get the water inside but once we did this little thing did a really great job of blasting away whatever was blocking the water pipes. You do have to be quick as the water comes out so draw it up from a jug or pot right next to sink and quickly place over plug hole and blast away! Fabulous for the price, worked a treat and saved costly plumbing charges!

Rated 3 out of 5 by from Drain unblocker not great but did the job after a few attempts to figure how to retain the water in the tube whilst it leaked at the same time!

Rated 5 out of 5 by from Magic! Very easy to use. Cleared the blockage in the basin after only 3 or 4 "blasts". Handy to have a partner to block the overflow as you need 2 hands to operate the plunger

Rated 4 out of 5 by from Did the trick Brought this as my kitchen sink was blocked couldn’t unblock it at all. Purchased this and it worked a treat sink was unblocked in seconds

Rated 1 out of 5 by from A useless product. This product is totally useless. There were no instructions but that was only the beginning of the problems! Once filled (in the bath, as too big to fill anywhere else) the water leaked out at such a rate that it was nearly empty by the time I got it to the blocked shower!! Then, when turning it the right way up for use, the rest of the water had poured out before it was in place. Absolute waste of time and money!
