I used this at the hospital and found it easy to use, so I bought one for myself. It attaches directly to the nipple, so there's no need to disassemble and wash it, and milk doesn't accumulate, which I highly recommend. The nipples are not included, so please prepare your own. You will need special nipples designed for direct attachment. There are no noticeable scratches, but please understand that this is a used item. Shipping may be expedited in some cases, so please consult before purchasing.
