Bloo Toilet Block Original Blue, Coloured Water In Tank Blocks, 4 x Cleaning blocks.

Best cistern blocks on the market by a mile

Excellent quality, effectiveness and ease of use. Very good value and service.

I recently tried the Bloo Toilet Block, and I must say, I'm quite pleased with the results. These blocks are fantastic for keeping my toilet clean and fresh. Each pack comes with four blocks, and they turn the water a striking blue, which adds a fun touch to the bathroom.The cleaning power is impressive. The blocks help prevent limescale buildup and keep the toilet bowl sparkling clean. Plus, they have a pleasant scent that keeps the bathroom smelling fresh. They are quite durable and offer great value for money.Overall, I'm very happy with the Bloo Toilet Blocks. They make maintaining a clean and fresh toilet effortless. If you're looking for an easy and effective way to keep your toilet clean, I highly recommend giving these a try.

They are very good but be careful not to put it on the right as it stops the water flow . ( I have tested 😅- follow the instructions!) put it in the left of the tank , that is it . Simple ! I quite like this products . Toilet gets clean every time you flash it. Horray !

These last very long, first time I am using a toilet block that has lasted so long and cleans the toilet too. I recommend

Love the way these blocks turn the water blue, 2 weeks in and still giving out a lovely deep blue colour - i will buy again

Ok but did not get anywhere as many flushes as expected (Manufacturers will probably claim that its due to the capacity of the cistern). Still better than the over rim versions.

Last quite a long time. I think they are worth it
