I have a G3 and it's a fantastic piece of pottery. My only small gripe has been the water capacity in the reservoir. I measured mine and it only holds 3.5 oz. The Dirty Bird is advertised at 12+ oz. Plus, the sides of the Dirty Bird are a little taller which would help hold the lather in. I have a Simpsons Chubby 2 and when the lather gets going off that bad boy, it often spills over the sides.
But, even at 3.5 oz of water, I'm still good for 3 passes. I fill the reservoir and bowl with boiling water from a kettle before I get in the shower and when I get out I fill the reservoir back up and it keeps the lather pretty warm.
My custom G3:
