DO NOT BUY FROM THESE GUYS. First they sell parts that are not genuine but "˜similar to…' i.e. Kohler etc. parts. The "˜similar to' parts do not fit and also leak. When I sent it back they said it was not defective even thought they never installed it themselves on a Kohler to find out. My plumber has installed hundreds if not more of these parts, I think he would know. Junk parts for the job!!! Do not use their parts. You will not get your money back as hard as you may try. I was told that since the parts bags were open they could not be re-sold…. Now how do you install something without opening the parts? Maybe they think I will let them keep the part and then they can restock it. Seriously we are not talking a lot of money here it is the principal. I guess I am just accustomed to better business people. The item is defective; they should return it to their manufacturer and not aggravate the customer. These guys are nickel and dime fools. Take your business elsewhere – Buyer Beware!!!
