## Questions & Answers

**Q: Does the Kelso prevent spills when the tumbler is tipped over?**
A: Yes, and you don't need to remember to close the lid! The Kelso tumbler has a valve in the spout, which lets water flow freely when kids are drinking, but stops spills if the tumbler is tipped over.

**Q: Is the tumbler easy to clean?**
A: Yes, both the spout on top of the lid and the inner straw underneath the lid are removable to make cleaning easy, and the parts are all dishwasher safe.

**Q: How old should my child be to use the Kelso tumbler?**
A: We recommend this tumbler for kids age 3 and up.

**Q: What kind of drinks can go in the Kelso tumbler?**
A: The Kelso tumbler is perfect for everyday cold beverages like water, milk, or juice. Thick smoothies are a little more difficult to drink with the valve, while carbonated drinks can build pressure and push liquid up through the straw.

**Q: Can I travel with the Kelso?**
A: The Kelso tumbler fits in most car and stroller cup holders for on the go convenience. We don't recommend putting the Kelso tumbler in a bag, as pressing on the soft spout can open the valve and allow drinks to flow out.

*by M***A on 5 October 2023*

Very poor quality, picture came off after few hand washing (I never washed in the washing machine), bottle it self is also very thin, is it not leaking, however is not keeping cold or hot at all. I would not recommend to anyone my child is very disappointed 😔 me too as not very cheap. The size is ok for little child but not enough for school especially during summer
