Today I got the GB 221 from Yingmin5. It arrived packed in bubble wrap only, maybe 7 layers? 9 days from China. So far so good. Got it unpacked, the top of the dome is uneven, with a chip on the bottom. The nail is only partially formed.
Don't care about the nail, but I might use the dome. I messaged him, using the "Dear friend" language that they like. I'm sure he'll replace it, but......the one I got has the MP angled more vertical than the pic, so it puts a nail right in front of one's nose.
The glass seems thick, the construction is good, no bubbles or obvious flaws. With the water just above the perc, it purrs nicely, I like the draw. However, even with a nail in place, a moderate draw results in a little bit of spray on the lips. Overall, not for me, I already passed it on.
