I have a Yulong and I think it's great! I lubed it with M1 and it performs close to my friends gts2m. The corner cutting on it is BETTER than the gts2m.
Cons: weak magnets, heavier than the gts2m, but it's great!
NOTE: I HAVEN'T USED A MF3RS2M BEFORE SO BIASED VIEWPOINT
I tried my friends YuLong v2m and at first I disliked it, but then it grew on me. compared to my main, the gan x, it feels similar, but definitely not as good. to be honest, even tho I haven't tried the mfr3rs2, id say it would be better, idk why.
