Day #1 - I was frustrated and regretting the order because of a couple things (below). First, you should know that I purchased this w/ the intention of increasing my supply...I started w/ producing approx 1-2 oz total/day, prior to this product. I currently collect around 5 oz total/day after using this for a little over 2 weeks.
1. The reusable container must be purchased separately. It comes w/ disposable bags only. This was annoying to me because I would produce around 0.1 oz per side and would obviously not store that for later. I was just excited to buy this so I overlooked those details and had to order the container a few days later.
2. I had multiple leaking issues during the first few days of use w/ both the disposable bags, and again w/ the reusable container - every drop I lost was devastating because my production was so minimal. There are videos in the app that are very helpful so I suggest watching all of them before your first session.
Give this a little time and you will learn to love it.
