This was my second aerolatte that I bought as they do so good froth. However; the design of battery holder and cover does not work. In both of models that I bought, after a few months the flimsy low quality metal contacts stop working and it is no possible to get it work anymore. Most devices use a steel spring or similar to make the contacts for the batteries and keep it. These devices come with a very thin metalic lamine that is too weak to work.I would not buy them again, I would examine another brand that offers a better design for the battery area and in general it should be better quality.
