So far so good
After researching and trying a few types of hands-free breast pumps, some are too strong (sometimes I feel like my nipples are being sucked away from my breasts), others is too weak (it caused the duct) then this one make me quite satisfied. Currently I am using the Spectra in the morning after waking up and at night before going to bed to be able to pump as much milk as possible, the rest I will use this pump.  It can suck about 7/10 if compared with Spectra. The suction is smooth, not too noisy.  I can do even my baby is sleeping. I think for this price, this pump is reasonable.
