“These lids work better than I'd anticipated. I've been a "Tervis" guy for a looong time, but I'm now a Tervis & Silipint guy. The cups are great for my kids, and they're nice in that they do seem to insulate. My stainless straw doesn't leak, and the seal around the opening that you sip out of (does it have a name?) works well too.
Hopefully the logo will stay intact through the lots of washing it'll get in the coming months/years.”
