Doc's Review | Aero-Yo Cold Metal CO2

A few years ago there was a brand called Cold Metal.  I always thought their yo-yos had a really cool look and style to them.  I got to try them here and there but never had a chance to own one or do a review.  Then the company seemed to disappear for a while until recently, resurfacing as a line under the Aero-Yo brand.  When the CO2 showed up on my doorstep, I tore into the package like a kid on Christmas day.


  • Killer tin can
  • Cold Metal Dog Tags
  • Poly String


Diameter: 54 mm
Width: 42 mm
Weight: 68.5 Grams
Bearing: C Sized bearing                     



Construction and Design:

Looks Great Looks Good Looks not so good
Color way options with silver splash Clean laser engraving in cup Laser engraving on outside rim looks out of place
Partial gooves in catch zone Standardized C-bearing and response
Excellent Packaging
Very “Classy” look


Aero-Yo has an incredible eye for acquiring talented player and designing killer throws.  The CO2 is the signature yo-yo of Alexey Nemchik.  The light grey splash on dark grey colorway is more eye catching than I thought it would be.  The CO2 also comes in blue and red with a clear silver splash.  About halfway into the catch zone, the CO2 has a grooved surface similar to the Werrd TLF or OneDrop Project.  The grooved area is not that wide though, and looks like it only covers the “grind” area.   The rim makes a “C” and the inside engraving has the “O2” on it, but it blends in with the grey and silver.  The laser engraving on the outer rim seems a bit out of place, but looks pretty good on the blue and red model.


Great! Not so great…
Smooth play
Grinds very well
Easy to hit catch zone
Snappy response system


You know that rare feeling when you try something that is everything you hoped it would be?  THIS IS EVERYTHING I HOPED IT WOULD BE!  I can’t deliver enough praise to the Aero-Yo on this yo-yo.  The CO2 has a clean long spin and a tight configuration that eases in and out of trick segments.  The grooved inner wall makes for a great grinding surface that reduces skin to metal friction.  The inner grind ring lays inside the cup cleanly and offers a great balance point.  I found the CO2 to play lighter than the actual 68 grams, but still heavy enough to roll into fast combos with an incredibly balanced stability.


Final Thoughts:

The Russian yo-yo company Aero-Yo has shot a blast across the Atlantic and from early reports, looks like they may be making a move into US markets.  If this is the case, American players can expect more great yoyos to choose from when that birthday check from Aunt Sally arrives.  The CO2 is a prime example of a unique design with popular features and excellent construction.

    John.. I may be wrong, but that Green yoyo on the left looks like a YYF Supernova.
