Review on 🥣 Collapse-it Silicone Food Storage Containers: BPA-Free, Airtight Lids, Collapsible Lunch Box - Oven, Microwave, Freezer Safe (Yellow, 6pcs, 2-Cup Set) by Ben Liu

I used to have similar containers so I bought more to complete my collection, but I immediately noticed a few differences when they arrived: (1) The vent part of the lids is a different shape (from the web images or collapse are the containers I have). And one of the lids (the vent part) got stuck on my countertop when I opened the package and took it out. When I tried to remove the lid from the countertop, the vent part detached from the lid! I managed to put the piece back in the lid but it came loose on the second wash - maybe the new vent shape isn't the best design? (2) has any of the 4 containers deformed due to poor packaging/over-pressurization? The silicone material seems to be the same as mine but for the (expensive) price I paid and the issues mentioned above I don't think it's worth the money so I returned it.
