I really wanted this product to work. Its very well made - german engineering. The concept is great - nothing to drill in the walls.I read the other reviews, and understand why some like and some didn't like. I spent several hours over three days, and discovered that it depends on the surfaces you are installing it on (ceiling and floor). If you are putting this on carpet, with a textured ceiling - something for it to grab onto - it works. If you are putting it on a smooth concrete floor (in your garage, for example), or a smooth piece of wood (like in an unfinished ceiling in your garage), the stand doesn't grip tight enough and tends to move slightly. Under the weight of bikes, and with vibration from the garage door opener, it can fall over.
