While they do have a "contact us" on their website, I have contacted them numerous times about a glass jar that is made to fit into their 2 quart yogurt maker. The jar does NOT hold 2 quarts. I have asked them repeatedly if they are aware of this, and if they have any plans to redesign the jar so it does hold 2 quarts. It should be designed like the plastic inserts where the sides are straight. This would also make it easier to clean. They have NEVER replied to my emails. I will be seeking out a jar that fits the yogurt maker on my own. Poor customer service. I will not be buying from their site and do not recommend it.
