Carbon Fiber Compact Key Holder, Premium Smart Key Organizer Keychain (4-20 Slots), Heavy Duty Minimalist Multikey Folding Pocket Keyholder, Durable Locking Mechanism, Slick Slim Quiet Profile

First off I'm going to say the issues one would have, have nothing to do with the product itself so its still a five star review. I essentially put three sets of keys together. One was two older car keys with a tailgate lock, camper keys(camper has like five keys), and all my house hold keys. The two keys that gave me the most issue was the safe key and one of the odd shape camper keys. If all your doing is straight flat metal keys you will have no problem. I took pictures compared to my multi tool. Also if your wearing standard jeans I'm not sure how comfortable it would be in your pocket. If you carry a bag or wear cargo pants you will be fine. And of course thickness depends on how many keys you try to pack on it. I did as many as I could. It comes with adapters. Also for the non standard sized keys you may have to drill the hole out bigger. Standard house keys, older car keys will be fine. Comes with Caribener for keyfobs and newer keys as pictured.

I've been using a KeySmart Classic | Compact Key Holder and Keychain Organizer (2-14 Keys, Black) folding keychain for about 4 years now, and I decided I wanted another. After shopping around, I found the Keysmart a bit more pricey than I'd like. I happened across this item in the "You may also like..." listing on Amazon and was willing to take the plunge on the less expensive SimpleBee. One of my motivations was to reduce the weight while adding an additional key (more on that below). Here are the like and dislikes I have:LIKES▪ LIGHTWEIGHT- It is, in fact, carbon fiber composite and as light and strong as that would infer.▪ FLEXIBLE in its assembly options (Carbon fiber is NOT flexible.) It includes 2 post sets with 2 sets of extenders in different lengths, as well as ~24 plastic/nylon spacer washers.▪ ATTRACTIVE - The carbon weave just looks good, especially in the sunlight.MEH...▪ The post hardware is a bit on the fragile side, and the threading is far finer than in the Keysmart hardware. Do NOT over-torque the post screws and use some thread locker if it seems like the screw might back out.▪ The provided post hardware is not compatible with KeySmart Expansion Pack with Screws, Spacers and Posts (2-22 Keys), in case you were wondering.DISLIKES▪ The white logo on the black frame looks dumb. I flipped these inside out, which is something you can't do with Keysmart.▪ The carbon fiber body/frame pieces are die cut. As shipped, they have raw-cut edges and are a bit sharp to the touch. I had to sand them down to a gentler, smoother edge using sanding pads (120>150>220).▪ The included plastic/nylon spacers are too smooth and don't help keep the keys closed in place. I used some fiber washers from the hardware store as a substitute, and they keep the friction higher between keys.Because I wanted lightness, I wanted to use aluminum key blanks. Sadly Amazon didn't have anything like them in their listings. The same aluminum key blanks that Keysmart offers (at $5 ea.) can be found elsewhere for a fraction of their inflated price. Do a Google search for "Mr Lock Inc" to find them for yourself. They look cool and the assembled set is about 40% lighter than the aluminum Keysmart with standard brass or nickel-silver keys. Keysmart makes KeySmart Lite | Compact Key Holder and Keychain Organizer (2-8 Keys, Black) which is lighter than their stock, but the flexible body doesn't strike me as nearly durable enough.I always like to have a USB drive with me, just in case. The Kingston Digital DataTraveler SE9 16GB USB 2.0 DTSE9H/16GBZ served me well on my initial Keysmart set, and I bought another to have on this set. It's water resistant and very durable, and perfect for this application. Hit up your local small hardware store for some small o-rings to fit in the post hole for a more snug fit.I added a couple of pictures of the assembled set for reference.

I have a couple of mul-t-lock keys and a key fob for my apartment building, plus mailbox key and a small chain lock door key. Not many keys but the mul-t-lock keys are big and awkward and the key fob itself is thick. It took me a lot of trial and error, and at first, when the keys were all smashed in, it was very hard to use, but I took the whole thing apart a few times before finally realizing the little plastic spacers are a necessity...they make it possible for the keys to stay in place and are still easily moved when I need them. Adding in the extra spacers (which required me to add the short extension to the long base screw) makes the simplebee just a tad wider (the width of the short extension) but infinitely easier to use. So if the keys feel like they require a lot of force to move or are pushing against each other in the closed position, consider adding the short extension and multiple spacers. Also in the final construction, make sure both sides are even in height.After a lot of trial and error, I found it best to put the key fob and the mul-t-locks on one side and everything else on the other side. My key fob works without needing to be moved and the mul-t-lock lock keys are thick and have plastic on them so I installed them without spacers between them, but they're so thick I needed lots of spacers on the other side. I am very happy with the final product, which was worth the effort. I like the look of the keys in the simplebee, much better than the unruly mess of keys I had before. It's very easy to use, especially when my hands are full.I looked at way too many brands of these before deciding on simplebee. Why did I choose this one.? I liked that it could be installed label side in, the two little holes on one end offer versatility if I wanted to add a separate loop in addition to the key loop, and finally the price is very good. What I received is something that seems strong and good quality.A couple of suggestions. The little clip it comes with is really small. I wish it were a tad bigger, but I do find it useful to clip knto my Gerber curve multitool, which has a relatively weak clip. Also, instead of a separate card multitool, consider changing the bottle opener to a multiool. A few construction tips would also be helpful. I was willing to go through a fair amount of trial and error but I like puzzles and putting stuff together. Other customers might not be so patient!Overall I am very happy with this and definitely recommend it!
