I use to get a similar product from tool carts. However, they do have small strips on the sides to better hold the key, which is an added bonus. The inversion allows me to make much better use of the drawer space. I don't understand the negative reviews, these are not holders, but key boards. I have both holders and racks and each has its own purpose. The holders are a little easier to pull out with the key than to twist slightly. Ideal for a stationary box.
