Query: The best frother

I was looking for a frother, with stainless steel pitcher. I was not disappointed when the frother came in. We are using it at my office. I love steamed soy milk and this is just the ticket. It is getting used everyday, sometimes up to twice a day. The milk is very hot, the froth is good and full. Customer service was excellent when I called about a problem I encountered. The owner was very helpful and the problem was me! I was over filling the pitcher and it spilled over a bit. Once I got my pouring under control, the machine works great. I just ordered the S14 to accommodate our need to make more steamed soy. Love this product.
