Review: I love it - I love it
Review: Amazing KeepCup - It was live from the first sight. The cup is extremely ergonomic, very comfortable to use. Leakproof, once I had it closed in the backpack with some coffee inside, and everything stayed dry. The cup absorbs coffee’s odor, even after washing it’s still there. But this will happen with any type of material except glass.

## Questions & Answers

**Q: What material is the lid?**
A: It's a rubbery feeling plastic (I think polyethylene).

**Q: Does this lid fit all Keep Cup sizes? I accidentally melted the twisting bit of mine in the dishwasher.**
A: I have many different Keep Cups and the 8 oz size and 12 0z size lids are interchangable.  I am not sure about the thermal, because mine dripped coffee - it did not seal properly - and it would drip on my clothes when traveling so I got rid of the thermal cup.

**Q: Is this microwave safe?**
A: This is the stainless steel version and would not be safe for use in a microwave.

**Q: How long does this keep your drink warm**
A: I did a short test using my 12oz Thermal, filled the cup with water heated to 163°F/72.8°C, then put on the lid and started waiting.  After 10 minutes it had cooled down to 154°F/67.8°C, 20 minutes 149°F/65°C, 30 minutes 146°F/63.3°C.  This cup would likely not be my first choice if I wanted my drink to stay hot as long as possible (I would instead recommend like a thicker double-walled vessel with screw-on lid, for example, a Zojirushi, Yeti, or Tiger thermos).  While I do generally prefer the KeepCup's drinking experience over a more traditional thermos, there is a trade-off in heat retention.

I think it is also worth mentioning that James Hoffmann did a similar test in his "The Best Reusable Coffee Cups - 2019 Edition" video on YT, at the 2:54 mark there is a chart of detailing insulation results for the various cups tested, including a 6oz KeepCup Thermal.  Per his test, and starting with water at 158°F/70°C, the 6oz cup was down to 141.8°F/61°C after 10 minutes, 136.4°F/58°C after 20, and 131.9°F/55.5°C after 30 - so it would seem that the larger 12oz Thermal model does have slightly better heat retention than the smaller 6oz cup.

### ⭐⭐⭐⭐⭐ Quality, keeps coffee hot.
*by A***T on May 3, 2020*

It keeps coffee hot, and it is not cheaply made. The lid doesn't acquire a bad smell like previous KeepCups. The lid is fairly easy to clean, and doesn't have nooks that cannot be cleaned unlike other lids. It is not leak proof, but it is better than a paper cup lid.
