Amazon Brand - Presto! WC Toilet 5-in-1 Rim Block, Ocean, 8-Pack (4 packs x 2 each)

These smell amazing, they are great value for money and easy to install.

Like these very much- my only complaint would be they don't seem to last very long if you only have one toilet for the family!

Although these were a very good price and they are easy to use, their staying power was less than other brands - I found they were used up quite a bit earlier than my previous brand. However, they are very good value even so, and do work effectively.

I found these Presto Ocean Toilet Rim Blocks very disappointing.The first one lasted for about 2 weeks and the last one I usedlasted 10 days.The dark blue sections drip liquid down the inner side of the toiletbowl every time you flush leaving a continual streak of blue.The paler blue sections last longer but not as long as one wouldexpect. Very little evidence of any fragrance.My experience over all is that these are poor quality and I will notbe purchasing any more.

Its really hard to rave about a toilet rim block, all I can honestly say is that it smells very nice not overpowering, it keeps the toilet clean as you would expect. Oh and it's very easy put together and attach to the rim.

Good value for money .Quality 7 out of 10 and way still better than other brands .

Was dubious at first but they are on par with other leading brands.Fresh fragrance & long lasting

I usually buy the usual brand name rim blocks and always buy them on offer so never pay more than £1 each.I thought I'd give these a go as they seemed a good price. They are completely useless! Each one lasted about 5 days, there was constant staining of blue going down the bowl under it and for some reason 'scum' seemed to build up between the rim and where they sit.I really thought they would be a similar quality but they are so bad and have such a negative effect, I wouldn't even use these again if they were free.Save your money, avoid and buy a decent rim block which does the job it's supposed to.
