Exactly how described
Very nice piece of tungsten.

Small but nice. Heavy.
Much smaller than anticipated. About the size of a dice. Is heavy. Well made. Just tiny. Ordered a bigger one after this

It's a Heavy Cube
I was hesitant to get this, since I wasn't sure how I'd use it. But then I got it and held it, and I knew exactly what to do with it: hold it. Everyone is impressed with the weight. They tell me "you have the heaviest .5" cube - the best, really." I can't disagree, it is impressively heavy. It looks nice, and it's very cubey. I'm tempted to get the 1.5" cube but I'm on the fence.

Smaller than expected but still cool
A bit smaller than expected but I should’ve measured I think for a gift it’d be a better deal to do the smaller pair of aluminum and tungsten cubes for ~$40-45.

small but very dense for its volume
small but very dense for its volume. perfectly rounded edges and corners and has smooth surfaces. at first i didn't feel this cube was tungsten alloy. because it just isn't heavy. but after measuring its dimensions, calculating its volume and weighing its mass. I'm relieved it is tungsten alloy. using the density shown on the spec sheet 18.02g/cm^3 and my calibrated digital weighing scale this cube's mass is 36.68 grams and its volume would be a bit less than 2.048383cc^3 or 0.125 cubic inch because of round edges. this cube's volume should be 2.035516 cm^3 or 0.124214 cubic inch. i would buy it again.

Is cube, is tungsten
It's a cube, not much to say about it. The machining is acceptable, the finish is nice, but it's not perfectly cubic; some sides are a hair bigger. Another issue is that it's not 100% tungsten, it's actually a pseudoalloy with ~5% each nickel and iron. That doesn't really matter though as it's still very dense. All said 9/10 good fidget.

Nice Collectors Item
Pretty cool bit of metal. I didn't think the weight was as heavy as it is, but it turns out the tungsten's density very close to gold (in the 19.3~ g/cm ramge). It's fun to collect various metals like this. Also turns tungsten is mildly magnetic; it stuck my rare Earth magnet hokey puck.

Gateway cube
It's small, it's dense, it's tungsten. This cube is superior in that the edges and corners are beveled and rounded off, as opposed to sharp edges on others you might find. I'd recommend getting the larger sizes, though, for a half-inch cube is not enough tungsten for any man.
