I have no claims against this company so please note that this review is not based on poor customer service or personal experience. Dissatisfaction of any kind. This also applies to all side drawers with soft close (I tried several brands). I'm also quite a practical person; I've built my own cabinets and furniture and have a lot of building experience, so it's not based on a newbie "trying too hard" on a project. These side rails are simply imperfect in nature. They are INCREDIBLY difficult and inconvenient to fit into existing cabinets. It's almost impossible to get them square and even. Once installed, they "stick" and are unreliable to use. They also break very easily in normal everyday use. If you want real, soft-closing cabinet drawers like the ones you see in model houses or on TV, you should bite the bullet and buy heavy-duty slides (Blum or similar). ). In my previous home, our new cabinet setup included a cheap Blum clone and they worked for five years without a single problem. These side rails were installed in our last home in less than four months and less than 25%. of these work perfectly. 10% of slides failed during installation. It was a $500 mistake. The same money could buy more than a third of the quality slides I really needed. Options: 1. Live with the rails you have and install reinforced drawer bumpers to muffle the popping noise.2. Spend hundreds of dollars on those poorly designed, failsafe side rails.3. Save your money until you can afford quality, ready-to-install splints that will perform flawlessly and last for many years. Just don't go there with these guides!
