This is the first hand pump that I have added myself - and I believe that there is hardly any better. The pumping time is with me no longer than with the electric pump; I had known, I would have been much more likely to buy them here! Because it makes no disturbing noises and you can take with you in a purse anywhere. I use it about 2 times a day. My hand does not hurt at all when pumping, think it's therefore not "hard" o. Ä. Also, when I initially took much the price, the purchase has paid off for me in any case. Only recommendable!
