Review on Ultimate Titanium KeySmart: A Must-Have Organizer for Men's Accessories by John Greene

I bought these directly from the seller. Recommended with two caveats: the system is designed for metal-based keys (as opposed to the plastic-based keys typical of most modern car keys), and you absolutely MUST use Loctite on all screw inserts or the connecting screw will eventually loosen and you lose your keys - i did! If you have more than 4 wrenches you will likely need a pack of extensions and should use Loctite on those screw extension inserts afterwards as well. Expansion packs come with flat washers, but I haven't used any of those. In my situation there were 9 wrenches total: My most recent successful system included an extended titanium and 1 extension pack plus a small bottle of Loctite applied to the threads of each extension thread and a final screw on each end. I also replaced the base of the vinyl coated car keys with metal. It would be better if the manufacturer included a tidbit of Locktite in its instructions, because judging by other reviews, this problem is not unique to me. However, the overall system is superb: well thought out (see caveats) and well finished.
