Hi, I just did business with them and everything went well.
I was skeptical about sharing my keys, as should be, but they delivered as agreed.
I sent my info per email last night and this morning I had a confirmation with exact amounts in my email and the corresponding amount of BTG in my Coinomi wallet.

I registered here now because I promised to give feedback. My profile on Reddit is hoisinABC and thats were I found and connected with wallet services.

Thanks!
