i got this for 10 usd kinda looks similar to the sleipnir, i unfortunately don’t have the sleipnir to compare it, performance wise it’s great but replace the bearing if you ever got a bearing that has a line that sticks in the back like a circular line it isn’t even the same as a cheap konkave you get from myy and that those are better than the stock bearing it came with, it’s fine in performance but it’s either A lubricated by the seller or B it’s just me. overall though the j1 is solid atleast that’s my first post about this yoyo so only 1 image i wish i can put more images in this post
