I LOVE THESE BAGS! I would definitely recommend to everyone!
Pros:
1. The bag itself is very strong and sturdy, much stronger than the L-name storage bags. It can stand on its own with no issue.
2. It has a temperature-sensing indicator, which is super helpful when you warm the milk in warm water. It warms up very fast too!
3. It has separate in and out channels so that you don't need to worry about contaminating the milk!
4. It has time/date/name/volume/notes 5 writing sections! Other brands only have 3 or 4 sections, it's convenient to include a note section and it's super easy to write on!
5. The bags came with a very good and easy writing marker.
I just love these bags so much!
The only con is even though you saw a perforated line on the pour-out spot, you can barely tear it apart, so I would recommend you prepare a sanitized scissor just to cut the pour-out opening.
