Very good mechanism

Easy installation and setup. The instructions are not the best, but it is obvious what needs to be done to install it.

Very good quality mechanism. Easy to install and adjust. It has everything necessary for its installation.

I installed it a year ago and I am absolutely satisfied
the package includes clear installation instructions

I followed the instructions, made many changes to the settings and nothing changes.
Dual function only because it has two separate buttons and nothing more.
To empty the cistern, you have to keep one of the two buttons pressed.
All the effort was for nothing…

One of the best flush mechanisms I have bought, it is very easy to replace, has stainless steel screws, and can be adjusted for the amount of water it will release. What you need to be careful about is that before you cut the plastic rods that, when pressing the button, activate the mechanism to release the water, you must first screw them in completely and then cut them, and by unscrewing them a little you can adjust them, although their margin is quite large.

I bought it to replace the old one which, due to limescale, did not fit well and was leaking water.
For the installation, the base also had to be changed so the whole cistern had to be removed.
For its own base, it includes a wrench, but for the old base I hadn't kept it and I struggled a bit to remove it.
I also changed the screws that hold the cistern to the toilet bowl. The old ones were better but if you remove them their rubber gaskets get damaged and you can't reuse them, so I used the new ones.
It has instructions for adjusting it (for more or less water), they are not very easy but if you spend a little time you'll understand them.
The (dual) button screws itself onto the lid. Underneath, it has 2 plastic screws that you can unscrew and cut to the right length so they touch the mechanism exactly. Essentially, this is the only 'modification' you need to make, the rest is simple assembly.

The package contains everything, the mechanism and its quality are very good. The instructions don't say much... But it's easy. The rubber included fit the old one that was already in the cistern, which was worn out. The button has two positions, you can set one to release a little water with low pressure and the other to release all the water completely. I had to cut the two plastic rods of the button to the height I wanted because they were quite long for my cistern, but this also allowed me to adjust the water pressure as I mentioned above.

I highly recommend it! In combination with HIlang Italian Group Bottom & Side Float 1/2 - 3/8" with Brass Base. It made a 20-year-old porcelain toilet tank fully functional... Like new!

It exceeded my expectations. The overall materials/parts are all of excellent quality. At this price, it should have no competitors.

Very good mechanism and relatively easy to adjust. It doesn't have very detailed instructions but OK, you can figure it out. It has everything inside for replacing the old mechanism, but if it also had the rubber between the bowl and the cistern (the old one is usually too worn out to be reused and fit properly) it would be perfect.

Very high quality and functional, it doesn't lose a drop. Easy installation. However, it takes up space and needs a float without bubbles to fit.

Easy to install - Excellent mechanism, especially in the use of dual flow for water saving
Recommended!!!!!

Good mechanism and easy to install. The only downside is that the button you press to empty the water is not secured anywhere on the mechanism, resulting in the porcelain lid wobbling a bit.

Very good mechanism for the money, easy installation if you have a bit of skill with your hands, I got it as a duo with the float of the same brand, ATTENTION the float is not included with the mechanism, it is purchased separately

One of the best mechanisms! "It doesn't break, it doesn't get damaged!" And most importantly, it doesn't leak! Not like the classic cheap ones with the bubble that leak immediately and you always have to come up with various fixes to make them stop leaking, and in the end, no matter what you try, they will continue to leak!!

Almost a month of use, it seems very well made, very easy to install and extremely economical compared to other similar products.

I have installed it for a few days now... So far so good. It seems to have a more solid construction compared to one I found in a local store for the same price (a big store and yet they only had one model to show me, the last piece, obviously the dual flush mechanisms don't move much in the market). The only "negative" thing was that it didn't fit on the old base (I would simply remove the old one and attach this one in a minute) and I had to go through the whole process of removing the toilet tank to install the new base... meaning dealing with silicone sealing on the gaskets of the base and screws, etc... hassle!

I don't know its durability yet, but it seems to be of good quality, the dual flow mechanism works very well.

Very good and high-quality mechanism. The flange that is placed between the cistern and the toilet bowl is not included.

Very good and high-quality mechanism!
It was installed by me (on ideal standard porcelain)
without any special knowledge of plumbing.
Keep in mind if the corresponding rubber gaskets are available from the previous ones, they might come in handy.

Quality materials, without tubes (that break), adjustable dual flow, compatible with all toilets. I installed it myself very easily. Much better than other much more expensive ones I had.
