Ideazon is best known for their Zboard- a keyboard that is made up of a base and removable keyset. A dedicated keyset is included for gaming and one comes for standard use- a novel idea, but something that take time to change and can get expensive if you start to buy specialty keysets. The MERC takes a standard keyboard and slaps a Fang Gamepad on the left side, but it can also be seen as the best qualities of the two Zboard keysets combined into one product.
With a retail price of under $40 and a street price closer to $30, the MERC is not going to have to offer a lot to impress consumers. That said, many people are going to resist any changes to something as familiar as a keyboard, so the price will not matter if the product does not stand up to expectations.
