The product is totally unacceptable, as it is a broken one. It did not seem to be broken during shipping. It's quite obvious that it is a broken item that was returned.

It broke just today. Not pleased AT ALL.

Easy to install, good instructions, works well.

Great product that did the work for replacing the old part

No t the right fit, attempted to return Twice at store, lines where too long, only one cashier, terrible customer service.

I’m sure this works great I had to return as I ordered the wrong one. I needed a 2 in and not a 3 in. The 2 in is the same brand and seems to be working just fine.

The fit was perfect and easy to install my toilet is now in working order

Why in God’s green earth did Kohler decide to replace a cheap, simple and effective flapper valve with this complicated, difficult to install, non-universal contraption? Their engineers need to be tarred and feathered.

I ordered the 3 inch Really needed it the 2 inch. Fortunately for me the main thing I needed was the canister and it’s the same size on both units. So with a little bit of ingenuity, I used the new canister and my toilet is back to functioning. I appreciated the fact that they happen to be the same size. And that’s the reason why all of my water appliances in my house are made by Kohler!

I had a few issues with the product:

The product that was inside the box did not match the product on the outside of the box… different shape and number. I had to order again from another place.

I was very disappointed to not find any instructions with this part. It didn’t want to seal by the gasket at first but was okay after a few days. Now it’s working fine.

The flush valve works as it should. The issue was in removing the old nut from the bottom of the tank. Once done, the new flush valve was fairly easy to install. It would be nice to have an easier chain and clip for the flush arm. Chain broke apart and the clip was difficult to clip onto arm. Needle nose pliers were a must. Perhaps, a better handy person would have less issues.

Had time old unit & making sure new unit was secure because didn’t have proper tools. Also, wasn’t sure it I would crack new unit tightening. Finally, got unit in place. It works great & very quiet plus lever extremely easy to flush. Found out later all I had to do was just replace rubber gasket. A.

Exactly what I needed! I really only needed the two gaskets that came with the kit, but I got this whole kit for around what the gaskets would have costed to order and have the other parts in case something else breaks. Super easy to install this way too.

Product was easy to install. The only issue is the picture on the box is not representative of the item. The top water line insert flange is different. So you just need to check that it will work correctly

As long as you throw away the water tube clip and press the water tube end onto the center receptacle at top of the flush column the flush column will seal perfectly every time you flush. Clipping the water tube to the side of the column cause the flush column to tilt slightly, causing the lower seal to leak.
