Danco HWK130 Toilet Tank Upgrade & Repair Kit

I recommend you do not purchase this product. I have used toilet repair kits in the past and I know how to install them and have never had problems until now. I installed this with the help of a friend, and a job that should have taken a couple of hours took all day with two of us working on it Ridiculous. 1. Extremely complicated with many different parts meant to do many different things I haven't encountered before. 2. Very poorly and cheaply constructed, doesn't feel like it will last long. 3. The directions were not only difficult and very confusing, in some places they were incorrect, or missing information or steps, i.e.: Position at a 45 degree angle, but didn't say a 45 degree angle from what. There was one point I called their tech support and he had no idea what he was doing and also gave us incorrect information. All this is what slowed us down for hours because we had to keep taking it apart and redoing it. 4. When it was finally finished and we figured out we had to unlock a piece the directions said to lock in order for the water to run, the thing didn't work right. The first flush left almost no water in the bowl; the 2nd left too much, 3rd not enough, 4th too much, over and over. The rubber valve closes too quickly. The thing is a disaster, and at a premium price for a disaster. I strongly recommend you pass this item up.
