Moyu RS3M V5 Magnetic Dual Adjustable 3x3 Rapid Cube, Without Sticker RS3M Magnetic 3 x 3 Rapid Cube, Professional 3x3 Rapid Cube(Moyu RS3 M V5 Standard)

This is a great affordable speedcube. It comes with a couple of replaceable parts and a tiny screwdriver for adjusting along with instructions on how to do that but I found it worked great for my needs right out of the box - though I might add a tiny bit of lubricant down the road. sides spin effortlessly but the magnets help it slightly lock in when they get to where they need to go which helps prevent the jamming that can happen when turning cubes quickly with the fingers. I do this as a causal hobby and find it difficult to spend $30+ for a cube so I've used a lot on the $10-$20 range and I can honestly say, this is the best of the bunch I've used so far.
