Not bad but not transcendent

I had the Avent manual draws milk. I was satisfied but I thought that with the power I would have a better result. It is not necessarily more efficient but the advantage I see is to have the opportunity to do something else while pulling her milk.
In the feature level with 3 possible powers, it is good (sometimes I qques pain and minimum power is then better suited.) However, it remains a little noisy at times and the engine block and stops for no reason.
I have not tried other pulls milk, although in this one imperfect functioning does what you ask him to do ... so I keep it.
