Review: Reviewed Feb 2025: Have had a few instances where the toilet was blocked due to huge logs, and even after 8 hours of bleach, could not move the moser.. After several flushes to make sure the bleach was gone, and no risk of mixing chemicals, I tried this almost in desperation. After a few hours, it had started to breakdown the contents, and after a flush, the whole lot moved and the toilet was back operational again. Much better, and cleaner than a plunger or using the wifes toothbrush to poke it free. Will by again.
Review: This is not as efective as the normal mr my me drain unblocker. Had to use two dosages and still not great. This was not a full blockage

### ⭐⭐⭐⭐⭐ Review
*by L***6 on 2 October 2024*

One thing you must do is to leave it overnight! I was surprised that it was quite thin, and not a gel type product like the usual drain unblocker. It did seem to have cleared the bath drain somewhat Would buy again
