Very enjoyable, of course if me are in the California, Texas and Arizona region. It's no longer complicated to shop, because there is already a delivery of a 'robot' delivery of goods without a driver, while watching television, we just order it online and wait a few minutes! the food we ordered comes straight to. this is a good program because it can reduce the burden of turning back to the market. I am proud of the company that created this 'robot'. But in our place in (Indonesia) there are no programs like this.
