Great little gadget if you have a lot of keys!

My husband really likes this.  I got it for him as a Christmas gift.  The seller sent me instructions on how to put it together immediately after purchasing, but he did not need them.  Holds almost all his keys, except his really bulky specialty keys for his safe.  He even has room to add a few more keys.  It's made of metal, so it will last for many years.

LOVE IT!!!

This is a little over priced in my opinion but still love using it. I hate the sound of keys jingling in my pocket and this solves that problem. It is a little harder to get your keys lined up and neat like they show you in the pictures but one you have them locked in it's a great accessory to have. Is slim in our pocket, no more jingly keys and KeySmart also has some accessories that go with his such as a USB or bottle opener. I use the two in one key ring so I can detach my car key from my house keys if i am out and about and want to have a minimalist feel.

Works as advertised. Great for key chains with lots of keys and cards.

This is the second gadget of this type I've purchased, and this one is improved over the first. I like it's small size (key-size) and that this one does not have a sharp blade towards the bottom. My first one does and I've cut myself trying to open it.  I knocked a star off because of the way it attaches to my key ring. It would be nice if it would stay on my key ring when I open it instead of falling off. It's a minor annoyance that wasn't enough to keep me from purchasing a second one. Overall, a nice little item that has come in handy on many occasions.

This is great for anyone that has to carry around a bunch of keys. Facilities folks at a University etc.

My wife has a habit of losing her keys and then I end up being the one trying to help her find them.  I felt like this was going to be the perfect item to help her and it has been!  It's Bluetooth so of course your phone needs to have Bluetooth (and if it doesn't what are you doing looking at this?) The app is a simple download from iTunes and will emit a beep from the tracking device until you stop the sound from your phone.  The App shows a map where the keys are but beware this is only connected via Bluetooth so the range is similar.  Great for your house, but not if you left the keys at someone else's house, etc.  Overall a very helpful device for finding things in your small Bluetooth radius so understand the limitations otherwise.

One note is that the slot to put the ring for your key is very narrow and I had to go through a number of different key rings to find one that fit and even that was challenging to put through here.  Wish it came with a key ring ready made.

I've had this for a couple of months.  I don't have to use very often because I **normally** remember to put my keys in the same place each time.  But it's great when I do misplace my keys because it saves me so much time!  Inevitably, your keys go missing at the worst possible time when you are rushing to get out the door!  I put the extra one in my pantry cabinet so it doesn't get lost.  I really really love the fact that they are a stand alone product.  I had considered purchasing something like Square, but then I realized that your location is visible to the company that makes Square and they potentially could sell your information to a third party.  I'm already annoyed that my smartphone is mining so much data about me!  Call me old-fashioned.  It seems pretty durable because the unit attached to my keys gets a regular beating with occasional drops on the floor.  I used the set up procedure to customize the initial alarm button and the double click latency.  It's so great I'm purchasing some for my parents and my in-laws!

This is a very useful product. It works very well but does have a limited range. Enter the danger. You sometimes have to move around the house to find the lost item. If you are one who loses keys, you might also lose the key finder. The first day after I received this set, I misplaced the finder. I hung it on a nail after a couple of days and have to make sure I always put it back. I would suggest a special spot for it or put a huge neon tag on it.

It is a great item and now that it has its own home, I am glad it's here. I have used it quite often and love it!

Of course, any key hook will do the job. This is simple, cute and wow, the idea of having a place for my keys must have saved me hours in the last years. I'm very ADD and really do lose everything. I have one habit of hanging my house keys, motorcycle keys, shed keys and misc keys on this thing, which is by my kitchen closet. As for rating of 5 stars... Well, its pretty much what you see, so how can I rate it as sub par? Its simple and works. If you don't get this key hook, just get one that looks good to you, the idea of organizing is what its all about. :)

Okay, I'll admit it.  I lose my keys.  ALL. THE. TIME.  I have a push bottom start car, and so I'm not always as aware of where my keys are, just that they are generally located somewhere within the car, or not.  I was constantly trying to find my keys inside my vehicle.  Did I put them in my purse?  In my gym bag?  In my work bag?  WHERE ARE THEY?!?!?  UNTIL.....I received this awesome key finder  Now when I'm trying to lock my vehicle and I need my keys to be outside of the car, I don't have to hunt around anymore.  I just simple hit the button, and the indicator on my key ring starts beeping for as long as I hold down the button.  There's no set up required.  It works straight out of the box!  It couldn't be more simple!  If you're on the edge about whether to purchase this or not, I would HIGHLY recommend it!  The only one who doesn't seem to like it is my dog!  haha!

This product is great for organizing an unruly and overpopulated keyring. It is best if you only put roughly house sized keys on it as larger car key sized keys tend to make the keys less accessible. Another concern is the tiny grub screw that holds one side of the organizer together. After about a week or two of daily use, the screw just kept coming out, leaving me with a pile of keys either in my pocket or if I was lucky, all over the floor. This can be easily prevented by using just a little bit of thread locker on it as I did, but it's still something that should have been addressed.
Either way, this is a useful product if you have about a dozen keys to look after so long as you have some thread lock lying around.

Very handy to have a flash drive that "unplugs" from your key ring.  For those of us who carry lots of stuff on the key ring, not having to leave your keys plugged into a computer USB port keeps from putting too much stress on the port or the drive.

I'm delighted every time I use my keys, honestly. This little device (particularly in the happy pink color!) keeps my keys in the most compact, silent, and durable space possible, while looking sleek. I use a standard 99 gas station carabineer to clip it on my jeans or throw in my bag for easy access. Make sure you have a clip/carabineer to use it if you don't want to stick it in your pocket. I can comfortably keep 2 large keys, 1 small key, a fob for door access, and the Orbitkey flash drive on my Orbitkey.

Great for keys that you need to remove from your keychain easily.

Very handy gadget. I use mine to hook my keys to the inside lip of my pocket so they hang inside and don't get bunched up in the bottom.

Keep similar keys on the same ring separate and easy to locate
