Fluidmaster Concealed Cistern 6Ltr is rated 4.4 out of 5 by 41.
Rated 5 out of 5 by from Excellent product Easy to fit and virtually silent in operation. If fitting in a shallow 200mm deep housing, you will need the right angle flush pipe rather than the swept pipe supplied, but no worries, it is stocked at Screwfix.

Rated 5 out of 5 by from Internal cistern Bought one of these internal cisterns to replace an old one for a customer. Went in like a dream no problems and up to yet no leaks! Ill have to see about reliabilty but being a fluidmaster i think there will not be any problems. Will buy this again.

Rated 4 out of 5 by from Fluidmaster concealed cistern Purchased this product because this cistern had really good reviews. Installing the cistern was straight forward and all looked well until I noticed water weeping from the flush pipe. The leak was coming from the pre assembled pipework and not from the customer side of the installation. "Do I take it back or (potentially invalidate the warranty) have a look myself" I thought to myself. I decided to strip it down and found that the internal seal around the exit pipe had pieces of black plastic embedded in it. Removed the plastic, dried all the components and flipped the seal over so that the marks where the plastic had been now faced the flush rather than the cistern itself. Refitted the cistern and all was well. Shame that poor quality control in the factory let this happen. Otherwise a good piece of kit.

Rated 4 out of 5 by from Fluidmaster quality Fluidmaster products are very good, and this is no exeption. Unlike many cisterns and components out there you can have some confidence in fitting Fluidmaster, its a brand I have come to trust.

Rated 5 out of 5 by from Cistern easy to fit! Once you've sorted out exactly how the cistern is fixed it's a piece of cake! Instructions on using the bracket would be easier with an illustration. More to the point, Lisa at Fluidmaster was very helpful and sent me a picture. I shall certainly try to use Fluidmaster products in the future, mainly because they helped!

Rated 5 out of 5 by from Was as easy as I had hoped. My old cistern had stopped working. After several attempts to try to fix it I eventually decided to buy this unit to replace it. Turns out it was a good decision. As other reviewers have said, it's all ready to install and use. With the benefit of the fittings that were already there for the old unit, it was relatively easy to do. I'm not a plumber but having messed about with the old unit, I knew what needed to be done, all pipework was already in place. Even the flush pipe was easy to cut. It's early days, but no leaks, efficient and quiet operation, all good.
