This was the first electric breastpump I had when I got put on Domperidone for gastroparesis and started producing breastmilk, even though I had never been pregnant before (one of the common side effects of this medicine). I kept getting breast infections, so my gyno suggested that I use a breast pump once a day to pump a little off to relieve discomfort and reduce the risk of more breast infections.
I bought the Nurture III electric pump, because of the many positive reviews and that it was less expensive than the other "premium" electric pumps on the market. This pump also has a 5 year warranty.
I did like that the pump was small and that I could control the suction and cycle for the pump, so it wouldn't be as uncomfortable to pump once a day. This pump is about the size of a small aquarium pump. It doesn't take batteries, so you have to have a electrical outlet in order to use it. This might be a downside for some moms at work or when camping and have no electrical outlet nearby. I didn't care for this pump for traveling for that reason.
I will warn you, this pump is LOUD! Its more loud than most of the electric pumps on the market, despite that it works way better than the ones you find at Wal-Mart or Target. I was taken aback by how loud the pump was, but I got used to it. The pump does have a lot of parts, including filters, tubing, and other pieces that are required in order for the pump to work. If one of these parts is missing off of one of the bottle setups, the pump won't work properly. All the tubing and pieces needed for the pump make it a bit cumbersome to use when in a hurry.
The Nurture III pump does allow single or double pumping, and like i mentioned above, you control the suction/cycle rate on the pump. I liked this feature a lot. There is a hole at the top of one of the bottle setups that you put your finger on and off of to get a rhythm going for pumping. It takes some practice, but after a week, its very easy to do. It cycle just as often as a Medela electric pump, according to the manufacturer. One other thing I liked is that this pump was compatible with the Pumpin' Pal hands free holder and breastshields, so pumping was more comfortable.
I used this pump for several years before I decided to just use a manual breastpump once a day. The pump was just too cumbersome with all the parts, was electric only, and the carrying case that came with the pump was just too big for traveling. Though this pump was wonderful in terms of suction/cycling and it was a reasonable price, I prefered my Ameda manual pump more.
