Does not recommend this product
I bought two bottles. One was perfect, but the other is leaking. I guess with a bottle that opens at the bottom also, it is possible to have leaks. I contacted their customer service to ask about the leaking bottle. They asked me to send them photos of the bottle and the caps. I did this. The lid and bottom cap were different between the two bottles I bought so I assumed the would send me replacement caps. After I sent the photos they never replied. I waited two weeks and still nothing. I emailed them again three days ago to ask for an update. They have thus far ignored my email. Could not recommend this product or company as a result.
