MantaRing - Cable Key Ring with Screw Lock - Strong, Flexible, Waterproof. One Ring for Keys and So Much More (Blue)

*****I really like this MantaRing and have had no problems with it whatsoever--it has never opened accidentally and seems very sturdy. It also was easy to use. I am currently using it to hold my stopwatch to a carabiner that clips to my pants instead of wearing my stopwatch around my neck--as such it works great! I would think it would be useful in any application in which you'd want a secure tie, especially threaded through a small hole (like the curved narrow hole on my stopwatch). I also think it's great that it's waterproof.It may seem a tad expensive for what it is, but getting it here saves me the trip to the hardware store as well as the cost of the gas, so it is worth it to me.Recommended.*****

I love the idea of this design. Unfortunately, the ring often comes undone at unexpected times. I switched back to a split ring.

I definitely find this easier to use than a traditional key ring & I love that it's so easy to detach and attach keys, but I have had issues with it loosening on its own, particularly when I attach it to something, like the belt loop on my pants or my dog's leash. I've never had it loosen in my pocket or purse, but my keys have fallen onto the ground several times when I was walking with it attached to my pants & I feel like it should be designed so it doesn't unscrew quite that easily.

I recently purchased some durable luggage tags. However the tags came with some not-so-durable rubber connectors. I replaced them with these rings and have been very happy with them. They are just the right size for the application, appear to be durable in any kind of weather and are not too pricey.

Update from week of 5.11.2015-Wonderful customer service. I let the seller know I hadn't recieved my order. They were extremely receptive and went above and beyond to make sure this was fulfilled. The cable rings are great. I've had others before...turns out they were a different brand. These are actually lighter weight and far more flexible. I have an annoying BMW key fob with a key ring option on the left and the right, but not in the middle. This results in a lack of balance when I use the fob as it is also my car key. My Manta ring is flexible and strong enough to "bridge the gap", so the fob and all keys attached to my cable are balanced. Would definitely recommend both seller and product.I'm sure this is a decent product. Happy to change my rating, but it appears the seller provided an untrackable number through USPS, and I will be ordering a different key ring.

Perfect replacement for a similar ring I found about 9 years ago. That one didn't have the plastic coating and the cable began to fray and stab me with it's super fine strands. That won't happen with this. This also looks pretty sturdy.. if anything more so than my previous one.The only caveat is you WILL need threadlock to keep the screw barrel from undoing itself. It would not stay secure without it and you don't want to be losing your keys. God help you if it decides to break free while you're passing over a storm drain. You might be able to get away with some low strength glue or some sort of 'sticky goop'... maple syrup? hmmm.. Ahem.. a stop at a hardware or auto store can land you some loc-tite, which will be useful in the future if you find yourself with a screw or two loose ;)

Love this Cable Key Ring. I have been looking for a simple way to remove keys from my key ring and came across this option and decided that I would give it a try. Work great and has not come unscrewed since I stated using it.
