How balanced are your dice?

So, this video by Daniel Fisher is going around the roleplaying corners of the interwebs.  Thanks to a golfing trick, you can check if the d20s you own are weighted. This might explain the myth of lucky and unlucky dice.

Apparently, translucent dice are better about being balanced and Chessex is quite an offender in cutting costs to produce dice. Well, no Chessex bag of dice for me then. I wonder how other companies compare.

I am tempted to check my own dice (and wondering if the other dice in the set would work), especially the Q-Workshop set, as they are considered a premium dice manufacturer. I might wait with checking my 3D printed dice until they are painted, because they might be a bit porous and quite frankly I don't want salt trapped inside.
