they could easily make it the same size as the key holder ...

It works... The velcro that sticks to the car seems small, they could easily make it the same size as  the key holder itself. As others did, I made a small slit in one end of the pocket so that my car key would fit properly, but that is not a big deal.

Lettering is rather small. There is plenty of room on the keys to make the letters larger.

It works as described. My only issue is with the size of the key slot. It's really only handy for a single flat house key. It would be nice if it would fit my car key fob in it too. Maybe a stretchy key pocket would accommodate a bulky key for a vehicle. Other than that, it fits around my arm well and adjusts to whatever size arm you have. I have a pretty large arm and it works well for me.

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. :)

Well worth the price. But it was too small for my car keys.  House keys fit well.  But the I have 3 car keys and only one fits in but hangs out the bottom.

I have already utilized the click 'n dig key finder and it worked great.  I was excited to put it on my husband's key ring as he loses his keys constantly.  Unfortunately he ended up taking it off as he doesn't like how big the finder is and that it is not an easy fit in his pocket.  Other than that, it's a good product.

small, looks like a key on my keychain, easy to open and fold

I bought this to put on my key ring and it's the perfect size for doing just that. It's made of metal, which is a must for anything on my key ring. I simply wouldn't trust anything made of plastic not to break. It's also made by Corsair, so you know it's going to last for a number of years without trouble.

Just beware -- it's really really SMALL.  So small that I wouldn't buy it again because it's really easy to lose.  The only reason I'm not giving it 5 stars is because the key ring is also so small that I can't get it onto a keychain and that is annoying.

Exactly what I ordered. It is a durable piece, and for the price, there is probably not a single thing better one could ask for. However, I give it four stars for its use as a key ring. 6" is a little bit large for me, and I will probably be looking to see if there are any 4" options out there. I got this mainly because I like the style and flexibility of it. Of course, if a larger key ring is what you need, this would be ideal. Although it won't be my day-to-day key ring, I'll certainly keep it around for hikes and vacations. Certainly I can use the lock to attach my other key ring to a back to ensure it doesn't get lost. Overall, you can't be the price, just be aware of the size in case you were looking for a more exact replacement for your current ring.

The picture shows the key ring with my keys along side the original placed in the middle. Hope this helps!

As everyone has already noted, the item picture does not match the product, but it is pretty close. The actual item is a 4.25" long pen type key with a small removable clip instead of a keyring loop.

I really wish that the knurled area on the key was much larger, but it stops at the brand name on my black key (according to the picture it is much larger on the "nickel" colored model, but who knows if that picture is accurate or not).

I had to grind the key down slightly for it to work in Vipertek cuffs, but it works fine now.

There's nothing fancy about this. Mount it on the wall, and you've got a key box. I was pleasantly surprised that it was a metal shell - for some reason I anticipated plastic - so it does give it a rigid, durable feel. I suspect this key box will serve us well into the future.

This key storage lock is well made and fits over the throat of a standard doorknob.  The interior of the  lockbox is amply-sized to accommodate keys of varying sizes and has two buttons, one for changing the combination, the other to remove the silver-colored lock hoop for easy installation over the aforementioned doorknob throat.  All in all, quite happy with this product.

Same size as original key, but we couldn't get keys to program, even at the dealer. They wouldn't connect.

Same as shown in the picture, easy install, it would be better if they could have a bigger size one.

Simple, cheap (1/2 the price of some of its competitors), and does the job its supposed to... holds your keys.  Only reason I gave it 4 stars is that the metal screw assembly is a little big in diameter.  I had to drill out the hole on each of my keys before they'd fit.

If your keys have the plastic coating on the head as on car keys then this wouldn't work well unless you only want to put one key in the holder. There is not enough room for thicker keys if you put more than one in  It's made for just regular sized key with minimal thickness.
