I wouldn't be happy with that binding. That alone means rejecting it. It should never have been sent to you like that.

The edge chips are bad if you are doing a light coloured or natural top. You could grain fill them and hope they look OK, but it is a compromise. I think I had some on my ES-3 but as I was planning a dark-edged sunburst I knew they could just be filled in.

You may be able to cure the other dent issues with a damp rag and a hot iron, or maybe a bit of scraping on the fretboard.

But also look at the neck angle. On mine and DarkMarks ES-3s, the neck angle is too low, and even with the bridge set as low as possible, the action is very high (4mm or so at the 12th fret). Even after filing down the base of a bridge so it sits on the top, and deepening the saddle notches, mine is still on the high side and the saddle is now making sitar noises, so I'm not at all happy with it.

So I'd check that neck angle, see what you think on the bridge height and if it's an issue for you, I'd just ask for your money back and forget about the ES-3 as a kit rather than get a replacement.
