## Questions & Answers

**Q: 2 stage lid is stuck. How do I get it to release?**
A: There are 2 tabs on the inner lid that the outer lid is supposed to engage.  At one point, my outer lid spun completely off and left the inner lid in place.  To fix it, spin the outer lid back on, and take note of where those 2 tabs are.  Then, when you unscrew the lid, squeeze the outer lid right where those 2 tabs are to force them to stay engaged.

**Q: Is this smell proof?**
A: Because it is water and air tight therefore it is smell proof.  But once you open it the wonderful aroma of your lunch escapes :)

**Q: Can I use the bonus bowl to microwave the soup if it doesn’t stay hot enough for me? I like my soup really hot.**
A: I'm not sure. It's plastic. Seems like maybe not microwave safe but I don't remember noticing if it said yes or no when I opened it.

**Q: How deep is the inside of it?**
A: Wide-mouth opening is easy to fill, serve and clean from
Durable vacuum insulated stainless steel interior and exterior
Cool to the touch with hot contents and sweat-proof with cold
Integrated full size foldable spoon fits securely in lid
Soft touch removable base for additional storage. Dishwasher safe

Great!! Very Happy !! Keeps the Food hot for 6 hours and warm for more than 10 hours!! Incredible

### ⭐⭐⭐⭐ Tough to open but works very well!
*by A***S on February 15, 2022*

Okay, I'm a woman with small hands. The cover unscrews in a dual mechanism that is supposed to help it vacuum seal. I have no doubt that it does that, but I can only get it unscrewed the first part by myself once there's food inside and then I need help to get it the rest of the way. So, I love it, but I'll have to be mindful to use it when I'm with others or get creative at getting my hand stretched far enough to get a better grip or something. The longest it has kept food hot for for me so far is 5 hours and I definitely didn't heat the food as thoroughly as I could have before filling it, but I did preheat the container by filling it with hot water for a few minutes. Edited to add: I'm a lefty.....the collapsible spoon seems like a great idea but omg it's infuriating as a lefty to have your spoon continuously try to collapse upon itself while you're trying to eat. I haven't found a way to get it to latch into place or anything yet but just thought I'd make you aware that you may want to plan on bringing a regular spoon if you're also left handed.
