Bison Tumbler Leak-proof Replacement Lid (GEN2)

The new lid has metal pins that serve as hinges for flipping open or closing the lid. This is a great improvement because my previous lid had plastic hinges and one broke. However, I cannot fully open my new lid where it will remain open because plastic tabs on each side of the channel protrude too far and prevents the lid staying open.

The lids have definitely improved. I've broken a few lids because they would get stuck on the cup, or start to leak because the seal wears out. The last ones I bought are better and can be tightened or taken off easily without leaking and should last a lot longer than the previous design

i haven't had it long enough to say, looks good, fits good

Love this, it keeps my coffee warm all morning at work!

Problem is:

I contacted customer support about a defective lid, but didn't get back to me as quickly as I would have liked (impatience) and I went ahead and bought one. Then the nice folks at Bison Customer Service reached out to me and sent one. Sooooo now I have two.
