broke off the keychain

It was heavy and the little connection on the end that hooks to the keychain broke, the pocket knife fell and was lost. It didn't last me more than a few months

Got lost on the 3rd day because of how loose the twist rings were:/ it fell off of my key chain at a store

The head was detached from the fur ball :/ But the head piece is gorgeous so I cut it off so I can still use it as a keychain :)

I really loved this keychain. Bought it for my boyfriend. He loved it. It even came in a cute box with a little saying. It was a legit looking keyring. However, it wasn't even on his keys for a week and the tie fell off the ring somewhere. We were so upset! :( it's not worth the money to buy a new one.

I attached this to my keys...at least four times it detached from the pin without my pulling it . Yesterday it went fling out of my hand and got lost in the bushes...but it is loud.

The break away key chain holding clip is much stronger than the last one I had. That last one fell off the key ring clip and I never found it again.

As many others have experienced, the KeySmart twisted apart after less than a week. One suggestion: Use hardware with nyloc technology or some rubber. The problem I had was the assembly loosening as I used keys and eventually unscrewing to the point where it fell apart. I tried tightening it down so it wouldn't unscrew, but then the components just sheared apart.

the chain broke after maybe two weeks, i picked heavy duty to make sure it would be strong enough for my keys. i have ten keys on my ring and did not want to have any problems. if you have more than a couple of keys this is not the key chain for you.

I've had this puppy on my keychain for months now and it's never failed to perform and hasn't wore out in the least bit aside from a few signs of wear on the edges from being sandwiched between other metal keys for months on end.

UPDATE: I no longer have this, it never stopped functioning, but somewhere around the 1.5 to 2 year mark i think the little circle at the end to put it on a keychain broke off. i ended up losing it.

The keychain is very nice and looks great, but a standard key has scraped off all the black from the key ring.

Love the key chain but is very poorly made. Back keeps popping off and the last time the art work got lost

The swivel piece fell of my keyring and I almost lost it. Had to squeeze it back on to create some tension.

Can come unscrewed (aka fall apart) while on your keychain.  And you can't Loc-Tite it because the screwing is the mechanism to turn the light on and off.

Used with keys on it. Paid a little bit of a high price for it. Not long--it broke. Looks nice, but poor quality and not durable. Very disappointed, as it was a gift to my husband.

The key case broke so I was able to use one half of this product to at least hold the key from firmly together

The pendant broke off the chain,  and I don't know where it broke off. So I no longer can wear it

It broke shortly after putting it on a key ring with other keys. The arms and hair came off almost immediately. Now it is just sitting on my Granddaughters dresser - She won't use it.
