I bought these so I didn't have to deal with the cheesecloth and rubberband tops anymore but the tops on these haven't been without their own problems. When they first came it took a long time to get the lids off. We still haven't been able to remove one of them. Using the other two has worked well so far but they just don't turn on and off easily.
Overall, a good size though and if the lids last I will be happy. Just now, I have a concern over their quality.
