OnCore Hydration Tumbler

I find it perfect. Perfect size and fits into every cup holder.

My wife washed my clear lid for the tumbler and one of the plastic side tabs broke off, so it falls off now. Is there a site for replacements?

This is a very nice tumbler, and it is generally equal to the Yeti tumblers that I have — with one exception! That exception is the lid, which leaks no matter how well it is seated on the top of the tumbler. The sliding mechanism on the lid is also a bit of a “sticking point” (pun intended), as it is very difficult to slide whenever you want to take a sip or two of whatever beverage you have in the tumbler—for me, it is generally hot coffee. Other than these lid issues, the tumbler works well and keeps beverages nice and hot (or cold), and it looks good!

Keeps contents cold for 18 holes. I love it

It looks great, but it does not keep drinks cold for long.
