Honestly, I was just tired of my old lid leaking everywhere, but this OctaLock one has been rock solid since day one. It clicks on with a satisfying lock and the Java color looks way better in person than I expected.

I was worried about compatibility with my 35oz tumbler, but this lid fits both Müv and Nav perfectly, and the OctaLock twist is so secure that I can toss it in my bag without a drop leaking. The Java color matches my setup nicely, and it’s noticeably sturdier than the original plastic one.

The OctaLock seal clicks shut with a satisfying snap and hasn't leaked once since I swapped it onto my 35oz tumbler. The Java color matches the rest of my setup nicely, and the lock mechanism feels sturdier than the original lid I replaced.
