Probably not a revolution in the industry but a great idea nonetheless. We’ve seen the traditional doorbell, tubular bells, birds singing, tune singing doorbells and a lot of kitsches, but this idea is totally new. Your guests are welcomed with a toast, provided by the ringing of these wineglasses, a beautiful tune for many ears. I’d say that at $150 it’s rather pricey but a cool idea to implement in a home, more for bragging then for permanent use.
