I purchased this the first week after my first baby was born and used every day for almost 9 mo after I went back to work full time. I loaned it to my sister who nursed for 5 months and I am using it again now, my second baby is almost 6 months old. I am just now starting to hear some faltering in the motor. It has been a great product and very much worth the price - particularly when compared to the cost of formula and other similar pumps. I have given it very extensive use and I would definitely purchase again.
