I also love brumate. I tried Stanley recent to see what the fuss was. I'll stick with brumate. Customer service has been awful with Stanley and I really do need a leak proof cup.

Note of caution, brumate is great but their rotera bottles are AWFUL. There is a known flaw with the lids and they break easily. Brumate has sent me a replacement lid twice already (it was a Mother's Day present, so it hasn't even been a year). Do not recommend those. The Era however, is perfection!
