A little report on my experience with this seller:
I've bought some Eugenia beaurepairiana seeds from Mr. Dada, and after almost 2 months I got the package with the seeds.
As soon as I opened the envelope, I put off my happy face for finally get my hands on this species, as the packing method was very weird, being a mix of cardboard wraped on endless tape. When I finally get rid of all the tape, I've found the seeds inside a small plastic bag, without any kind of media, or moisture to keep them alive, and already showing signs of mold on the seed skin. As the seeds were incredibly lightweight I puted them in water, and none of them sank, so I decided to broke the skin to inspect the state of the embrio inside, and it was completely rotten, showing a lot of mold.
I contacted Mr. Dada explaining my situation, and asking for a refund, and for a week or so I got no answer at all, yesterday I sent him a new message, and he said that he sent seeds for other people as well and nobody complainted; sugesting that I should have no reason to complaint, or that I should be happy with what I got. I sent him another message, asking for refund, or otherwise I would publish it here, as I got no answer, I think Mr. Dada it's not interested in refunding my money, so everybody must know how this seller deals with his clients, and how he cares about what he sends out for other forum members.
Bellow you can see some images that show, what I got from him:
