The other thing with an insulated container is that it can perform 2 jobs, namely keep liquids hot or cold for hours which means it can be used year round. So if I want iced or cold brewed coffee during the summer, I just continue to use my insulated container.Absolutely right! It’s not a price thing. I just don’t feel comfortable buying one and then replacing again and again and again to keep my drink warm over time. It’s just not environmentally friendly to me. I get the convenience of it, sure and I’m sure many enjoy it!
The Ember can only keep liquids hot, and only for as long as the battery has a charge. If there's no charge, the liquid will cool down quickly since it's not insulated.
