The cube itself is good, and is probably the best keychain cube. However after 2 weeks of using it on my keychain, the clip that hooks into the cube snapped off leaving me with just a very small 3x3 instead of a keychain cube. I'd still recommend it but just know this might happen.

GAN never ceases to create high quality puzzles, if you want a 3x3 to add to your keychain this is the one you want, it's smooth, built like a speed cube, and it looks pretty cool. You will not regret buying this over any other keychain cube.

This is a great cube that is small enough to fit in a pocket so you can take it any where. It comes with a keychain but I find it easier to just slip in my pocket, it is small enough, and I always have a cube on me when I need one.
I am still a novice with cubes and am no where near a speed-cuber level (average 10 minutes!) but am slowly learning. Having a cube always on me helps with that.

Definitely buy it, it’s extremely cheap for the quality. Just keep in mind there’s no magnets.

GAN330 Keychain Cube

This keychain 3x3 is perfect to bring with me everywhere. I take it out to turn a little at a red light or while waiting for my wife to do grocery or pick up food. I used to bring my regular cube with me but now I don't have to. Pretty convenient.

Got this mostly to round out my growing collection. Really wish they made a magnetic version with out the keychain so there isn't holes in one of the corners. Turns surprisingly well for a such a small cube after adding a little lube and loosing the tensions a bit. It was tight out of the box, probably to be safer in a pocket.

My friend had one and I liked it so I got one, big fan. It turns better than most 10% Rubik's cubes and is really cool and portable.

This cube is almost identicle to the MFJS 3cm cube. It holds lube for longer and has slightly better corner cutting, but not $3 worth. Unless you are buying it because it is a GAN cube, you should probably get the MFJS cube instead.

I wanted to get a cube that was cheap, decent quality, quiet but also one I could put in my pocket to take with me wherever I went. That’s when I came across this fantastic little cube. Now I am not a speed cuber, I simply picked up a cube to help curve some nervous ticks to give me something to fiddle with. What I do know however is it’s a pretty quiet little cube and it doesn’t make any clicks or grinding noises. It’s quiet fast for me (I do wrist turn occasionally), and it has never locked up or popped any pieces. As mentioned in the title this is my very first cube and I love it. I used TheCubicle’s YouTube video on cube solving and after a month of practice and this cube I can typically solve the cube within 7 mins, my best time was 4 mins 12 seconds. I don’t think this would be an amazing cube for most serious cubers as it is quiet small and can be very hard to position for quick turns and algs without your fingers getting in the way but for a fun little puzzle on the go that is fluid, quiet and can be slightly adjusted to fit your preferences, 100% great little cube.
