I just bought a new 220G. I have no real baseline for comparison, but I was quite pleased -- black silicone, well applied with no sloppiness, arrived without a scratch anywhere.
I am not terribly pleased that the base was not tempered, I worry a bit how much rock I can put into it. But that's more worry than known issue.
It's typical glass so it has a lot of green in it, but that's what I expected. If you want the fancy starfire glass you have to pay a lot more.
