Absolutely loved these key holders. I hate having a bunch of jingling keys in my pocket and the color coded rubber covers don't last. I need my keys for work and this was the perfect key tool. I can hold all my keys plus a box cutter key. Fits slimmly in my pocket doesn't cut into my pants and I never set them down and forget about it. Best key holder tool on the market. Got one for my Operations Manager as a stocking stuffer!Made things compact and less cluttered. Took a few attempts at lining keys up for perfect closure.Didn’t work well with color coded key ends they were not square enough for the key alignment.Nice key organizer. The carabiner was different than the one pictured.I was looking for a new way of organizing my housekeys this seemed a very smart way and up to date. They’re all the same this type of key system was nice fully organized but after a week of using this product it got very annoying. What i mean is and being honest the key casing scratches the key fob leaving marks. Most importantly the time you flip out the keys you need to unlock and open your doors i always felt like if a thief was behind you then the 2 minutes of fumbling to open your door versus having traditional key chain. Just my two cents on what I experienced hopefully everyone else enjoys this product.Looks nice, not too heavy when you add all your keys. Being able to hold the whole thing and turn your key as if it was a screwdriver is actually kind of nice and I think I’m faster now going in and out. Great product from a smart thinking company!I like this item. It makes your keys more compact and not dangling all over the place like with a traditional key ring. It took some maneuvering to put the spacers in for my thick car key but once I figured it out it works well.Not quite as tough as I expected. Installation was a little more tedious than I expectedNice key organizer
