There are a handful of reviews here from people who don't pay attention. This is one carabiner and three key rings, so disregard reviews complaining about it not being 4 carabiners.I've had them for 10 months now and I honestly have zero complaints. They are so much more sturdy then a standard key ring which is the main reason I bought them. The carabiner makes it very easy to hand off your key to a mechanic without having to fiddle with key rings. The sturdiness does make getting keys on the rings a little tougher then a normal ring but once everything is on they are great.The only reasons I'm not giving it 5 stars is the price is pretty high for what you get and because the color fades quite fast and that will upset some people. I personally like the bronze color that is beneath the paint so this isn't a negative in my eyes.I'm very pleased with this key ring and yes it's maybe overpriced by a few dollars. I'm not sure how people would think all 4 pcs worked the same, the pictures are very clear on what you're purchasing. I've been carrying this for a couple of months with no complaints.I travel a lot between home, raves, road trips, and flights so I'm always switching out my set of keys.If you never switch your keys out this is more of a vanity buy, but if you do swap out your keys often, this is a must have.I like this carabiner so much I ordered 4 more. I love the style of them, very sleek and functional and fit my sleek minimalist style. Definitely recommend this productMain spring on unit failedI like that I’m able to keep my keys organized on the key rings, and I’m able add/remove sets, easily, to have minimal pocket presence. The product looks good, but after a few months the finish is starting to wear to a copper color underneath. Overall, it’s a good product.This mechanism is beautiful and well crafted. But it’s not easy to clip on and off of items since it is so round. I didn’t return it because Ilthe item itself works but it is so inaccessible to unclip my keys from my bag that I have to put the bag down and use two hands every time. Carrying a bag and coffee and a mask etc ... I purchased to have my keys easily accessible but this actually adds another step for me making it annoying. It’s now a pretty addition to my junk drawer. Sad really because it is well made.The big ring has a strong spring in the hinge that prevents loss of the 3 rings it carries. My car fob, house key, and good luck/protection charms each hang on a separate small ring from the big ring. When someone needs to use my house key, it is easy to remove from the hinged larger ring. Same goes for the key fob if someone needs access to my locked car. This system is a very convenient way to organize. No worries about something falling off of the sturdy larger ring, either. Absolutely the best "key chain" I've ever owned, and I've had many decades of experience. ;)
