No idea - I don't have them. Sorry I can't give you a more informed opinion. I will say that I'm fully satisfied with the Mr. M and I don't want any other 5x5s. I'm not serious about 5x5 though - I just solve slowly for fun.
What magnets would you recommend for the Meilong 5x5? I am aware you used 4x1.5mm N35 throughout the cube and I have watched your review on the 5x5. Is there anything you would do differently to the 5x5 in the magnetisation?
Those who got it early on Cubezz and The Cubicle are probably still awaiting their packages. Looking forward to seeing some reviews on the product as well as how it compares to the Valk 5M
Edit:
Just realised it's only $20 compared to the $50 Valk 5M
