When I first saw it I declared the HaymakerX to be Duncan's version of the Draupnir. I made a quick overlay to test my theory and, looking at it along with the specs, the HaymakerX is definitely Duncan's version of the Draupnir. The differences are extremely subtle: a very slight concave in the profile to decrease string contact, and a weight increase of 1.8 grams -almost certainly in the steel rims.

This yoyo is utter perfection. It's deader than dead smooth, ridiculously stable, offensively nimble, and spins like nothing else I own (on a matching bearing). The finish is amazing. Like actually amazing. Grinds are super clean, and the flat hub and V-shaped body make finger spins almost automatic. Like I said, perfection.

I used to keep a couple yoyos out for easy access -my favorite players so to speak. The ones I most enjoyed and most often played. A few days after I got the HaymakerX I put them away. It's just aggressive enough to give you that bad ass feeling when you land every trick with ease, but it's still chill enough when you just want to relax and have fun.

I haven't said this since the 80's but, once again, my favorite yoyo is a Duncan.

This yoyo is very much worth the price , it has a beautiful finish great rim weight distribution and it feels insanely good on string , i feel like i could use this thing forever it doesn’t stop spinning it sounds beautiful by far one of the best in my collection don’t miss out !

I'm in love with this (YoYo) I have bought 8 yoyo over the past weeks & this one is Smooth~Stable & the most powerful one of them all, it's (SMOOTH) feels like butter in my hand, Worth every Dollar/Get you 1 your going to love it......

My Haymaker X spins with such balance that you can't even really see it spinning at all-- absolutely no wobble or vibe. The rims give this incredible lateral stability, which can take a few minutes to get used to if you're used to a "floaty" style yoyo. It powers through anything, and keeps spinning through long combos. It comes with white response pads, which aren't as grippy as I like (I much prefer Duncan's red pads to these), so I'll probably silicone it myself soon. The finish is smooth and works great for grinding.
Very much a work of art!
