So after using the cups, here's what i think:
Cup Size
KeepCups are available in many sizes. Mini, Small and Medium.
Personally the one i have is the latest 'Cork Edition' that only comes in Small (8oz) and Medium (12oz).
Material
There are the plastic range and these glass range. If you are intending to hold really hot beverages, my advise is to get the glass ones. After using the rubber one and the cork edition, the cork edition will definitely beat the rubber one hands down, because i have very low torrance for heat and honestly, the rubber do not help to offset the heat, it is only for a better grip.
However, for the cork edition, you should be careful you do not spill your drinks or coffee onto the cork area to prevent staining of it.
Heat Retention
The heat retention ability is not bad, my drink is still warm after an hour. But this is NOT a thermal flask, so please do not expect that your drink will still be burning hot after leaving it inside for awhile.
Overall i'm happy. I'm currently using it when i make my old beverage or coffee. Stilling trying to explore how to pass the cup to the barista when i order coffee from a cafe! Will definitely try that soon. Just worried that they will stain or dirty the cork area.
