A few months ago these were on special at Coles and I decided to give them a try. I have tried quite a few different toilet deodorisers and this one works as well or perhaps better than most I've tried. Yes I definitely recommend this product!
Easy to hook over the rim of the toilet and it looks funky and colourful. However, it does not seem to keep the toilet cleaner longer than when I had no block cleaner and the scent is very faint. In future I'll do the manual clean a bit more often and get a better result.
