Query: Aerolatte - Excellent but Battery Intensive

Just purchased my second aerolatte (first lasted 3 years before it started running down batteries too fast). Excellent for frothing steamed milk (I put 8 ounces in microwave on high for 1 minute), then froth. Very similar to "caffe con leche" in Spain. Product has been reliable --but does take some "touch" to avoid spraying milk around the kitchen. Expect 2 double A batteries to last about a month, using 1-2 times a day.
