Addicting and (mostly) Durable
Totally in love with this Infinity Cube fidget, it's super addicting and easy to manipulate in a variety of different directions, similar to the movement of Baoding balls. Also looks identical to the fidget found in the new Tron Ares movie used by Julian Dillinger. The weight is nice and heavy, though it takes some decent hand/forearm strength to operate fluidly (my gf's opinion was it's too bulky and heavy for her to use comfortably). The toy itself is very durable given the all-metal construction, only needing a single pass to tighten screws when I first started using it (it loosens up a bit). However the color coating starts to wear immediately around the edges and corners.

Awesome fidget toy, feels great in the hand, and has some weight to it!
I have a lot of fidget items at my desk both at home and at work - spinners, sliders, clickers, magnets, etc. and I like to mix it up, using different ones depending on my mood. Sometimes it helps me just clear my head a little to fidget with a random item and this Infinity Cube by Lifidea makes its way into one of the top spots of my favorites! This infinity cube works great and feels premium in my hand, it has a solid amount of weight to it so it really feels good as I’m fidgeting with it, almost like a mini workout for my fingers. I love that it’s made out of aluminum and not plastic as I had a plastic infinity cube before this and it felt cheap/flimsy when using it. The movement of reshaping the cube into different configurations is great and has a satisfying sound of the aluminum pieces hitting each other (just don’t expect to use this around other people and not annoy them) so I like to use it when no one is around to be bothered by the sound. The infinity cube came with a carrying case, a mini hex wrench to tighten the screws/joints and some extra screws which is nice to have just in case one happens to fall out and get lost. I don’t use the carrying case because the cube just sits on my desk at all times but it’s a nice little bonus anyway. Overall, it’s been a great experience using this infinity cube just when I’m clearing my head or mindlessly zoning out. I’m very impressed with the overall quality and especially the weight of this cube, it’s now in one of my top spots for fidget items!

Great, Durable but Heavy Metal Fidget
Silver is definitely the color to choose. When I read others' reviews indicating that the points of contact on the fidget wore away the paint, I bought the silver, thinking it was not painted at all, but instead was the natural silver color of the metal. I appear to be correct. You can see in the picture how there is a smooth area at the point of contact, but since there is no paint, it is not really noticeable. As for the fidget itself, the motion is loose/easy and I am able to use it with one hand. As the parts collide when moving it makes a satisfying, but not noisy metal-on metal "clapping" sound, similar to what I would expect a metal Rubik's(r) cube to make. Note, however, that that sound will irritate anyone with auditory sensitivities (though probably ALL fidgets would do that). I find both the motion and the sound to be addictive.

Great Fidget, Wears More Than Hoped
super awesome fidget, i've used it a ton both at home and on the go, the weight is awesome, the feel too, and it's fantastic for when i'm pacing thinking about something, absolutely awesome fidget and i plan to buy another at some point so why 4 stars? it wears a bit. small gripe, but the wear makes it look silvery, like the anodization comes off, and i have to dock a star for that since i'm very picky about fidgets. otherwise it's perfect, and a great price.

Time and time again this fidget toy has proven to be superior.
I love this toy. I’ve bought several over the last few years, for myself or as gifts. They’re a great weight and very solid. I love that it comes with the hex key to tighten the screws. Yes, the screws will loosen with time, but that’s just in the nature of how it’s used so the hex key is a great idea. You’ll probably see the paint fading in some of the other reviews, but again, it’s in the nature of the use of the toy so it’s not a big deal. I also love the worn look it gets when you use it. It’s a great fidget toy and I’ve loved every one I’ve gotten and will probably continue to buy them as time goes on. Maybe I’ll get one in every color.

A sturdy Infinity cube worth far more than what you pay for it.
I have always enjoyed infinity cubes. They are very relaxing and help me focus when I'm struggling at work. I wanted one that was sturdier and had weight to it because most infinity cubes are plastic and tend to wear out quickly with heavy use. The Lifidea Infinity cube is sturdy, has nice weight to it and still fits my hand well. I was surprised by its quality compared to its cost. It also comes with a tool to replace bolts as needed tighten them up if it becomes to loose, which is even more of a value. I'll be following this brand. They don't have a lot on their store yet, but if they add new items I'll want to check them out.

Best fidget on the market!
Quality of this is great. I was tired of the plastic ones breaking and I’ve had this one for a while now. I like how the metal is smooth and it’s a little bit heavier, which is nice. If you find it on sale, it’s a great price point. The best fidget I found to help me focus!

Very nice and addictive fun
Ordered silver to avoid anodized color models from wearing off. Then I checked for loose screws, which were quite a few, some very loose. All of this based on other reviews so not unexpected. If screws loosen up after use I'll add a bit of blue Loctite on first couple of threads under screw heads. If Lifidea were to do this it would probably bump up cost I'm very pleased with this products value, addictiveness, size and smooth operation. Recommend for sure.

I love this cube, it does a great job of occupying a fidgety hand and I often use it when thinking through a difficult problem. The metal feels very nice on your fingers, and the weight gives it presence that lighter cubes don't have. This also makes it a lot more work for your fingers, so your fingers may get tired and you'll need to use it slower if you are used to lighter cubes. The joints have very little flex and it folds with a satisfying snap. I've dropped it several times and the worst that has happened is one of the screws coming loose, which the included hex key fixes easily. One thing to note is that the paint wears off at the contact points after using it for a short while and will give it a weathered look. I quite like this look as it shows how much Ive used it, but if you don't like it then I reccomend getting the unpainted silver one.

If you like infinity cubes, this is the infinity cube. Made of machined metal, it's nice and weighty and feels sturdy in the hand compared to plastic ones. The major thing I rave about are the pins. Literally every infinity cube I've ever had has had friction-fit pins that degrade over time. I'm autistic, this thing is in my pocket 24/7, and it does not wear out at all. It comes with a little Allan key in the case, so you can tighten the pins if they start to loosen, but I've only had to do that once. You're probably balking at the cost. Don't -- This thing will outlast every one of your other infinity cubes by a factor of 10, especially if you're a heavy user like I am.

High quality, all metallic parts (no plastic), nice weight, smooth movement straight out of the package. Best infinity cube I’ve tried so far. Spare parts and tools are handy as well.
