Bests & Worsts Reviews from Amazon

I've been using these fairly regularly for the last month. General use - storing leftovers in the refrigerator & reheating. The rubber seals that (I'm assuming) are supposed to stay attached to the lids almost always get stuck to the glass containers. Generally not an issue, I'd just pull it off and put it back inside the lid. I always remove rubber seal prior putting in the dishwasher or microwave. This morning the rubber seal ripped into several pieces when I attempted to remove from the glass container. Super bummed. I still have the other ones intact - HOPING this one was a fluke, but my feeling is they won't be far behind. Without the rubber piece, the lid won't seal properly. This was not due to mishandling these - I'll still get good use out of the glass dish, but wish as a whole unit it would've held up better. **edit - 2 more of the seals have broken since my initial review. If you're looking for glass tupperware WITH lids that seal closed, I would look elsewhere.
