I have used Purse a few times now without any problems. My sister has used it a few times as well. I had tried the other one... Brawker a couple of times and both times testing it out on a Macys purchase and also an eBay purchase and while they both worked out fine, the buyer on both different orders acted strange to me, wanting me to release funds early, release partial funds, etc. Weird stuff and not needed as their BTC price was locked in. Never say never but I doubt I will touch Brawker again.
