Review on ZLR 3 Sets of Silicone Sealing Rings for Instant Pot 3 Quart - Red, Clear, and Blue - Compatible with IP-DUO Mini 3qt, IP-LUX Mini 3qt, IP DUO Plus 3Qt - BPA Free by Rene Carrell

The rings seem to be made of good silicone. However, the rings I received didn't cover my Lux mini IP properly. IP reached pressure but then all the steam came out of the lid. Check out the video I posted. I tried all three rings with the same result and put the original ring back in place and didn't have this problem. On closer inspection, these new rings are slightly larger than the original IP ring, resulting in an inadequate seal. Maybe I just got a bad batch or the IP looks smaller than most. However this is still one star for me as the description says the rings should work for IP Lux.
