This is a bridge I purchased around June. It's made by Musiclily and is a copy of a Gotoh 510 bridge. The string spacing is 10.5mm. It took about a month to arrive after ordering. The saddles were cheap and a different color, so I replaced them with brass gold ones. These are also Musiclily brand. The block is made of steel, so it seems like it will resonate well. The finish feels smooth. The bridge construction is better than cheaper ones, as you'd expect for the price. There are some minor scratches and what looks like paint chipping from when I bought it, but they're not very noticeable. If you're concerned about this, you might want to reconsider. I will disassemble it for shipping.
