MoYu MeiLong 7x7 V2 (Magnetic)

I'm not sure why this cube is priced so low. It has amazing performance, and it's possibly my favorite cube. I would highly recommend it for both casual solvers and top competitors.

For the price, this is a great cube to start for a 7x7. The magnets are not super strong, but the cube still has a good feel and smooth turning.

It isn't as nice as, say, the MGC or X-Man Spark, but is a good cheaper option. You'll be happy with this purchase and hopefully develop a feel for the next upgrade.

the cube itself is good with strong enough magnets to allow middle layer turns with one finger, but when turning and individual slice, it is hard because the pieces are small and other slices can move with it.

Good and cheap

The Moyu Meilong 7x7 M V2 is also an improvement over the original Meilong 7x7, although surprisingly not as good as the 6x6 M V2 for me. It's pretty tight out of the box and needs set up to get it to a pretty decent budget 7x7. I've never had the chance to use the YJ YuFu 7x7 V2 M, but I feel like with the size difference and the price, it can be a better offer than the YuFu. I would really recommend this for beginners, specifically for those just getting into 7x7.
