Hi I just purchased from her last week. She's very responsive and willing to send more photos. She didn't pressure me for a sale. The items were packaged well and shipped fast! If in doubt of authenticity, she can also email you a certificate from Zeko's Authentication.
I do recommend that you ask to see photos of any accessories that come with the item you're interested in though because the box that I got was not the original box of that item. It was still a vintage Chanel box, but the item code on the box sticker was for a different bag. It wasn't a dealbreaker to me though because the bag itself was accurately described and that's what I really cared about. However, if you want a true "full set" ask for more photos.
The biggest pro for me is that she is based in the US so the price you see is what you pay + overnight shipping, assuming you are in the US also. You don't have to worry about unknown customs/duties compared to buying internationally or your package getting lost moving from different countries.
