ONE MONTH UPDATE: the pain has started to wear off on the corners individual cubes. Have been using about a half hour daily. It's still sturdy and works well, but I'm taking a star off because it really shouldn't be wearing like this after just 1 month.

Pros: made of pure alloy, color/texture is consistent, satisfying action, hinges are solid so far (1 day in)

Con: may be a little large to manipulate one-handed for smaller hands

This is the real deal. After seeing other products with bad reviews about inconsistent materials and colors, I chose this cube. The picture shows its weight and relative size. Very satisfying to play with, even the soft clicking it makes. This replaces a (long broken) Lego infinity cube I had made. It seems very durable, and I'll update if it breaks in the future.

The only minor knock against this lifdea cube is that it's pretty big, about double the size of the Lego cube. If you have small hands, it MAY be a little tough to manipulate one-handed.

Very soothing and diverting. Highly recommended.

Solid aluminum blocks and metal hardware. Nice weight in the hand compared to the cheaper plastic versions. And with each link screwed together, you can go wild taking it all apart and reassembling if you want. I actually found one link that was installed backwards and stuck out a bit further causing abrasion, so that was both annoying and fun to remedy. Good idea to tighten each screw before playing and periodically to ensure they aren't loose. But they stay put otherwise and make for a more sophisticated infinity cube!

I have a similar Infinity Cube to the one I bought, but it's all plastic and very light weight. I thought I would enjoy this one better and so far I have. I found the action to be very smooth and pleasant to manipulate. The rounded edges are easier on my hand than the plastic one with sharper edges and the weight is nice and heavy. My hand actually gets a bit tired after 10 minutes or so of single hand movement, but to me that's an added benefit since it's like a "light" hand workout.

After a week of daily used I have noticed some of the edges getting a little worn already where the edges make contact with each other edges, but I think that's just the coating of the cube and won't affect the handling of it. Seems like the cube pieces aren't a "solid" color, but rather painted over a lighter color. I would have preferred to have it be a solid color as I really like the color, but it's not a huge deal.

The kit comes with an Allen wrench and two replacement screws, along with the case that is surprisingly well finished. I found that roughly half of the screws were a bit loose, so I tightened them. Tightening the screws doesn't seem to have any effect with the smoothness of the movement, but if I find that they continue to back out though movement I'll remove the screws and put a little blue Loctite on them to keep them in place.

Overall, I'm happy with the product and would recommend it. 4 stars due to the wearing of the edges and that showing a lighter color.

It's pretty much exactly what I was looking for. I just wish it was a bit tighter.

I had a plastic fidget cube and didn't care for how it would occasionally get stuck if I didn't move it exactly right, but this all-metal one is very smooth and I can mindlessly manipulate it while reading, watching TV, etc. I also find the physical weight of the item quite grounding (it weighs about 6.5 oz., according to my kitchen scale), which is helpful to me for reconnecting to my environment. I have not tried to take it apart yet, so I cannot comment on that aspect, but I appreciate being able to customize the colors as required.
