Query: Manual pumps are too hard to use!

I'm sure that this pump measures up well to other manual pumps, but I cannot stress how much harder it is to use than an electric/battery operated one. I have an Evenflo hand held one which cost about $30-$40 and is great. I pump once per evening. And at work I have the Medela Pump in Style, which is a double, heavy duty pump and is quite a bit more expensive, at around $270. But worth the extra money for lots of every day pumping. My doctor warned that manual pumps are not worth the hassle and he was 100% correct in my opinion. I got this manual pump as a gift. I tried it several times before giving up for lack of patience and time, trying to get it to work properly.
