KeySmart Pro, Key Organizer with Tile Smart Location

Only buy this for an enemy. And if you have any other keychains to attach --for car keys, remotes or key fobs that it can't hold-- the KeySmart multiplies its many curses. The key design problems are that several parts serve dual --but conflicting-- purposes. These are: the two key posts, and: the loop that attaches the KeySmart to other keychains. Before the daily torture begins though you've got to suffer through assembling the diabolical thing. Getting a stack of keys onto either post requires a surgeon's steady hands. The receiving post on each end is stubby, so assembly can require holding a stack of keys, in a precise position, upside down, with a stack of washers interspersed, while aligning it to the other half, and screwing the two sides together (with your third hand). Tiny bouncy washers are provided as spacers, but it's unclear how many to use initially, or where to place them so the keys on opposite ends don't interfere. Trust me: once you have it assembled you won't ever want to do it again. Yet the whole mess flies apart on its own accord all the time, so you will. Now welcome to the first fundamental design flaw: those double-duty posts on either end. Each post has a screw and receiver paired to pair with it. The post's two purposes are, a) to attach the two halves of the KeySmart together; and b: to give something to loop your keys onto. These dual purposes mean that, on the one hand, the two halves need to be tightly assembled. Yet that makes the keys difficult to pivot outwards. Yet if screwed too loose, the keys can flop out, forming a jumbled throwing star in your pocket, and can quickly unscrews itself spontaneously, scattering keys across the ground. You might find a Goldilocks tension, yet it changes. This is because to access any key you, you pivot it outwards, and this very act frees up space between the two halves and lessens the tension on the screw. This action gradually loosens the screws over time. Check all the time to be safe, else your keys end up on the ground. After suffering multiple episodes with the KeySmart spontaneously disassembling itself I leaned towards overtightening. This left pivoting the keys out an awkward ordeal, sometimes a two-handed job. Put your coffee and other crap down on the ground, because you're using a KeySmart now! The second --and even worse design flaw-- is the asinine double duty that the keychain loop serves. It's required to use it, because -- bafflingly-- there's absolutely no otherway to attach a keychain. In lieu of a hole they offer a metal bottle opener key ..with a keychain hole on its opposite end. This bottle opener/key loop is to be stacked in along with the rest of your keys on either post. Choose carefully though: because the side of the bottle opener has a nightmare in store for you. The problem is when the bottle opener pivots outward --say because you're accessing the neighboring key and it followed along-- the hole end of the bottle opener then pivots *inward* into the KeySmart's innards... dragging any attached key ring and keys along with it. The bottle opener may catch itself on another keyloop, perhaps fighting the key you're trying to access, or another that tightly follows its motion. The result is hellishly entangled jumbles of keys and chains. Even with two hands, it wasn't always clear how to undo the rigid mess. Instead of opening a door, you'll found yourself presented with an unexpectedly confounding topological puzzle. Attempting to free any one element might only further jam something else in the Rube goldberg. I should've taken a video, it was almost comedic in hindsight. And it happened all the time. Eventually I removed the foresaken bottleopener-cum-keychain-loop altogether, and instead attached a regular circular keychain around one of the posts. This was better, but still awful. The contraption still bound itself up, just less diabolically. And the KeySmart still always slowly unscrewed and disassembled itself. I finally gave up, tossed all the KeySmart washers, and just kept the Tile half of it. Now it tracks my backpack, and on my keychain, I use a normal Tile. I don't miss the extremely feeble LED light the KeySmart came with either, the only other feature I haven't mentioned. Don't be lured by the marketing. The seeming LifeHacker-ish appeal the KeySmart pretends to hold is not there. Your life would be better never having heard of this thing. Heed my warning. Just get a regular Tile instead.
