I haven't heard of them myself so I don't have an opinion however when gold gets sold in small amounts the mark up is much higher compared to buying standard one ounce gold coins. When you sell it they will only offer you melt value which is the spot price minus the buyer's overhead and profit.
The solution for little people like myself is to but silver that has a much higher potential to double or triple in the near future. A one ounce silver coin normally carries a mark up of two dollars over spot at any local coin shop and in my opinion is the best investment out there right now for either a millionaire or common people needing a shelter for their hard earned money.
