Which is the best breast pump in the market? Any suggestions, mums?

I recently picked out a Medela Freestyle Breast Pump on Amazon.com for a friend here in Sweden. It is a compact, lightweight breast pump with a 3-hour rechargeable battery for mobile pumping anywhere. This daily-use breast pump is designed for moms who pump several times a day. It includes thoughtful features to personalize your pumping experience, including 2-Phase Expression technology and has two sizes of Personal Fit breast shields for comfortable and efficient pumping, I found the pumping timer feature very useful - it allows you to conveniently track your pumping sessions and there is memory button so you can easily return to your favorite pumping pattern.
