Overall
Overall, everything is great except for the following things: * The promo codes work strangely and do not apply to the bulk sale. * The filaments are packed very well, maybe even a bit strangely: first in a large box, then each small box is wrapped in plastic, and after this small box then another layer of plastic. But that is probably more of a plus. * The filament quality is excellent, although I have not tried everything yet. If it were not for the strange region lock on the website — if you choose the wrong region at first, the cart gets reset — and the slightly unintuitive interface, I could probably give it 5 stars. For now, an honest 4 stars.
