Been using Smart Key Holder for about a month and love it. Before this one, I have successfully broken two predecessors by snapping the screws ( different brands). This is the one that’s holding on so far. I would however speculate the quality of different brands is roughly the same. Through my previous experience, the key to not break the screw is avoiding over tighten. This seems obvious but I found that if you have two keys on each side, one washer in between, and use one extension–> you will have very loose keys flipping around and you will tend to over tighten the screw in order to secure the keys–> then you snap the screws. The easy solution is to use more washers (eg 2 or more between the cover and 1st key/the last key) so before you put a screw on you feel the cover is barely covering the end of the extension. Thus you only need a little tightening force to make the keys really snuggle and secure, and you avoid overtighten. As you use the keys, the screws will slowly get loosen overtime, I found myself needing to re-tighten the screws slightly after one month of use but really no big deal.
