Probably works great for keys

This item is okay. I primarily ordered it to use the locators on my remotes but the sticky pads do nothing to help the rounded locators stick to a rounded remote.

it could hold up to 5 keys max., the screw size is too tiny to hold more than that. it is misleading to say it can hold 10 keys!! it is over priced as well.

I'm sure it functions fine when it's used, but I never got that far because I lost it within a week. That little clip does not do its job very well. I'd recommend a keyring can over this.

It works ok when I have only my id badge and two keys, or just my 5 keys, but with everything on my keyring at one time it won't stay retracted. As i walk, the keys weigh it down and it hovers half out. I'll be looking for another one that is a bit stronger. If you only need an id badge or one key, this should do the trick.

No really much to say about this, it's relatively small so you probably won't be able to get it through a wheel, the frame, and a locking post. However, I don't have quick release wheels and I don't live in a place prone to stealing so it works for me. It comes with 3 keys, one of them with a little flashlight. The key can be a little finicky but I'm sure it'll become easier with time.

Worked really well for what I needed it for. Bought a new house in the country and it came with lots of keys. This was a quick and easy way to organize keys and even the men in my life can understand. Isn't made out of the most sturdy plastic, but for us it will work well.

Got bulky for keys, good quality, clip doesn't seem the best wouldn't trust keys to it

I like this - I've even forgotten that something was hidden in it ! Great for safe keys, etc.

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.

It certainly does fit my 88-key keyboard, and I like that it's machine washable, but it would be nice to have it designed *just* for 88 keys, because it's a little too tight.

Slightly more convenient than your average keyring

Bought this to affix a hidden key on the underside of my deck, for the pet sitter to use. I cut a small, thin piece of wood (about 2"X3"), painted it the same color as the deck, put two pieces of velcro on the underside, velcroed the key to the middle, and also put velcro on the deck. The wood is held on with the velcro, and the key is hidden underneath the thin piece of wood. From afar, it's not very noticeable that there's an extra piece of wood there, with a key under the wood.

But about the velcro: The actual loops and hooks of the velcro surface do seem to be "extreme." It's kind of a metal-looking surface, rather than fabric-like of regular velcro. (In the photos, the pieces on the two sides are "extreme" and the key is held on with regular velcro). However, I suspect the weak point will be the adhesive holding the velcro onto the wood, and that doesn't seem to be any stronger than regular velcro.

So, since my key isn't used very often (I have used it myself a couple of times when I've locked my keys in the house), it'll probably work fine. Until the adhesive starts going and the velcro comes loose, and then I'll replace it or think of a different way to hide the key.

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.

This product will only work fir single keys on the little key rings provided. If there are multiple keys or normal sized key rings they will not fit. key fobs, rubber ATV keys, key chains, multiple keys are all out. It is a decent unit if you have multiple single keys to hang.

It's pretty big for hanging on keychain.. twice as big as my keys. So I bought another one that's smaller and gave this to my husband.

This works pretty good for the keyless start (push button) car key although it's kind of -- ok, very -- obvious that it was designed for the switchblade type of key. That is the only reason I knocked down a star since it would be nice to have some way to "tighten up" the fit for the non-switchblade keys. Otherwise, everyone always asks about it, especially my Service Manager who wants to consider bringing it into his parts department to sell as an accessory.

I'm using it on my keychain primarily for switching out car keys with the option of hanging it off my belt loop if needed. I've only been using it for a week or so now, but so far it's worked out pretty well. The only thing I can see being a potential problem is pulling the black plastic piece (the lock) out to far and dropping it. I also bought one for my wife for her keychain, so I'll update if either of us have any issues.
