Rough workmanship, after-sales attitude shirking responsibility, and now basically none of the domestic agents are German. The price is high, and you cut corners everywhere. The error rate is very high. My cupboard has been returned to the factory for seven times because of various problems, which cost more money than others and caused various troubles. Now my feeling must be that I chose Koehler, which means I chose disaster. For more than a month, all kinds of shirk their responsibilities, importune, do not solve problems for customers, and do not admit their design mistakes. After returning to the factory for repair and replacement again and again, you just have to apologize verbally and ask you again directly. Maybe choose the toilet. Their house is not bad. I think their family's experience in this kind of thing is really lacking and not worth it. First of all, the cabinet panel has a brand, and the same product on the market is much cheaper without his label. Most of the cabinets are structured, with almost no big boards and pitifully thin backboards. The hardware doesn't belong to his family, just like the countertop, it is contracted to other companies. I remember that the countertop was DuPont's, and DuPont's countertop was bought outside at half price. Finally, after-sales, because everything is patchwork, once something goes wrong, it will be passed on to other manufacturers, and then, if you wait, there is no future.
