Plays quite well. Finish is good, response is just right and it's well balanced. It doesn't feel quite worth the price tag. The plastic feels ok but not like top of the line and the two part construction feels like it's prone to separate with a good smack. Don't regret the purchase, but wouldn't buy another

If you’re into fixed axle and 0A tricks, this is the yoyo for you.

Love every bit of this for modern responsive play, super comfy and smooth. Matte finish is great for tape measure style tricks too. Most importantly, it can shoot the moon. Very well too.

Nice! Absolute banger!

MK1 and Spinworthy recently teamed up again to make the Plasm, a polycarbonate version of the RBC. This new version of the much-loved throw features a tweaked design that works better with plastic and is available in a range of cool, translucent colors. I was lucky enough to have MK1 send me one to put through its paces, and I can say that this yo-yo is an instant classic.

I’m going to preface this review with the fact that, unlike many, I am not a big fan of the RBC. It’s a beautiful throw, but I couldn’t quite figure out where it “fit” as a yo-yo. Unlike the wooden Blood Cell, a Spinworthy original, the RBC wasn’t made for fixed-axle play. It also felt quite awkward as a 1A responsive yo-yo. Again, I’m in the minority here, but other than how cool it looked, the RBC just wasn’t for me.

The Plasm is a completely different story.

I could immediately tell upon my first few throws that this yo-yo is far more capable. The catch zone is a bit larger, the shape a bit more forgiving, and it plays both 0A and 1A styles beautifully. It’s super comfortable in the hand and has a wonderfully satisfying response. You can feel the seam of the cap more than you can on the RBC, but it is by no means a problem or a distraction. The changes MK1 and Spinworthy made to take the RBC into the realm of plastic made a world of difference in how playable the yo-yo is.

Whether I’m Makin Da Zines or Skinning the Gerbil, the Plasm handles it all with ease and comfort.
