dackdelSweet.
Thanks to your review the next time these drop, I will buy 4 more.
They are so bad I need to have them for every single key.
That's how horrible they are.
Again, my children you saved from the apocalypse of shitty quality, thank you.

OK, so these are actually great. I didn't know what to expect, but these are really nice.
I manage apartment buildings, so have 15 keys plus a Nitecore Tube flashlight and a Gerber mini pry bar on one keychain, and nine keys plus a Ghost mini flashlight and a mini Swiss army knife on another keychain. That's a heavy set of keys, and this device holds the two bunches together.
It's been great. Needless to say, I'm pulling out my keys and using them dozens of times a day. This device secures them really well. Plus the quality is top notch. Really well made.
Previously, I had been using those little magnetic key quick releases that dropped here on Massdrop a while back. The little teeny ones with the super strong magnets.
Well, compared to this spring loaded one, those magnetic ones are bunk.
First off, the release weight of the magnets is significantly lighter than this model. While it holds OK, the magnets just don't feel secure. This one feels much more secure. No fears at all.
But the biggest flaw of the magnetic models, though, is that once the two halves are separated, they will instantly stick to anything on your keychain that is not an aluminum key.
That means each half will suck onto your mini pry bar, or keyring, or sub keyrings. And this will happen every time.
Which means every time you want to reattach the magnets, you have to peel each magnetic piece from whatever it's stuck to (that's 2 pieces stuck to 2 different surfaces) and keep them free and clear amidst your myriad of keys before you can reattach them again.
Try this a handful of times each day, and you'll be done with those magnets.
So this Kappa one is the way to go, IMO. Once these drop again, I'm in for a few more.

Yeah but no reviews or anything. I've seen them on Amazon and considered picking some up but I have no idea what the detach force is, what metal it is, anything

Lol. Yeah, I've had this type of inexpensive quick release key chain in the past. It's the kind you'll find at Home Depot, or just about any hardware store.
Because the little plunger button is attached to the keys, and because my bunches of keys are so large, I've had a few instances where the quick release would unlatch in my pocket from pushing and jostling while in my pocket.
So I stopped using that particular kind.
I imagine it would work fine with just one, or a few, keys on each side, though.

I bought these with a custom logo for my company from Prometheus for our employees' year 1 gift. They are fantastic — heirloom utility pieces. So I'll praise them a bit. I don't like chotchkes, the usual knock-off nalgenes with a corporate logo, or Yet Another Moleskine Notebook. So I wanted something that would likely still be around for the length of the company, setting off a tradition of useful, functional gifts. We gave each employee two so they can make better use of them. I couldn't be happier with them. I use mine to detach and throw my office keys in my back pocket when I go for my lunch run, or to swap keysets with my wife when we swap cars. Anyway, I can't offer comparisons or evaluations other than just a stellar endorsement that these are worth every penny.

octavecatGreat post and picture.
Just got home and almost missed this by 14 orders.
Buying one for now.
I believe I'll want more, just for me sadly.
But thanks to you today, I know I need at least one.

Bought all 3. Never again!The Copper one is broken the others are so difficult to separate that it defeats the purpose. Spend $3.00 on EBay and get a good keychain!

My Favorite is the Delrin Black after(the not this drop) Titanium QR.
The Delrin is denser and more durable than the Lexan, and it's Black :).

ChelemboundHi, I'm surprised to hear this as we have near zero QC issues with the Kappa. Feel free to contact us at support@darksucks.com if you'd like assistance.

Always liked the idea of these things; just never was willing to risk the loss of half of my keys!

Sorry about your loss... theft can feel like a heartbreak.
A flashlight and the tiny knife are the only things I really would need to pull separate from my whole keychain. I open mail packages a few times a week, and in my last job I used a knife to open boxes at least 20 times a day, plus I learned the value of illumination and having even a small light with me. Made a habit, I suppose, but I still never got to the point where I carried pounds of keys that I never used!

i'm kiiiiiiinda worried about the detachment gets easier over time "feature". but i guess it happens.
a path more traveled has no grass.

bsastorYeah, that reduction in force over time is concerning. I was going to use this for a climbing harness for my hamster, but not so sure now. 😀
Actually, I'm sure it comes heavy, but stabilizes to a certain level.
I'm going to get one for one or two extra keys. I know that if I tried to secure a multi-tool with something like this, it would be gone in short order. There's just too many opportunities to snag it on something on my everyday life.

Are these able to be use one-handed ( am amputee) without too much difficulty?

OneArmedGraphicsI think it might be a little difficult as it requires 10lbs of force to pull. It's not crazy hard but you definitely have to be deliberate in separating them. Not sure if this is helpful, but if I were to use two fingers on the same hand I might have a difficult time at least when it comes to pulling them apart. You might be able to separate them but you could run the risk of the item it's attached to flying out of your hand because of the force needed to separate these.
I'll say this though, they are MUCH nice than that push button style and they're smaller in size as well. If you don't mind running the risk of throwing away $20 they are very nice.
Hope this is helpful.

Not exactly the same as both using different QR mechanism. The Tactical Keychains MQR is using magnet, while Prometheus Kappa QR uses canted coil spring.

Based on Jason's Instagram post some time ago, he hinted that he won't be doing the Kappa QR in titanium. You can refer to this link https://instagram.com/p/BBa9soJtYNM/.
