I ordered 1g of FXE and O-PCE 6-7 weeks ago... took forever to hear back from him after payment was sent, and then was told it's out of stock (even though he keeps listing as in stock). Instead he sent a couple grams of K to hold me over until more FXE was in stock, but now it's been another month and still no FXE.
I did also order 3mmc, which showed in 2 weeks... have no idea of the quality but it's getting lab tested in the next 2 weeks or so.
Overall, this vendor is responsive (sometimes have to repeatedly email to get a response though). However, the delivery time and service has been all over the place.
