I could not afford an electric breast pump and our insurance did not cover a rental so I decided to give this one a try. It actually works pretty well, I was surprised how much I could get out with a manual. I was very easy to clean and changing the bottles out was simple. Not difficult at all to put back together either after washing. Only reason I gave it an 8 is that my hands did tire after a while squeezing the handle. This would be great for a mom who does not need to pump a lot. Comfort It was very comfortable on the breast, just uncomfortable squeezing the handle after a while. Good hand and forearm workout! Ease of Cleaning Super easy to take apart wash, sanitize and put back together. Even sleep deprived I had no issues with cleaning it at all. Durability Seemed to be very durable. I used it throughout the day and at night and it held up well for me. Versatility It's small and without all the tubing it's versatile enough to use anywhere. Ease of Use Easy to use but the squeezing of the handle becomes tiring after a while.
