I received mine and I'm very impressed. Blade gap is around 0.80 so it's efficient. I wouldn't call it smooth - it's a very direct shave. I got some blade feel and audible feedback but no irritation, so I'd call it a success. I did a shave off against my Merkur Progress set at roughly the same gap and the Progress was quite a lot smoother with less feedback. Efficiency was very similar.
I find the handle is an issue - it's too long and heavy for me at 100mm, 12mm and 80g. I may try and cut a bit off the end of it. It looks great and I assume it's brass, so if you like a heavy handle it's a good deal. The head is clearly Zamak at 32g. It's nicely finished and the blade sits accurately. At the price this is a very classy razor. My solution to the handle is to swap it over with my matte black Yaqi handle, which I really like. That's 91mm, 12mm and 66g. It's pretty perfect for the Yintal head, balances well and is good to hold. This is a Frankenrazor which I like using quite a lot, and right now I expect it to have a worthy place in my rotation.
