Quite happy with mine although I have to measure out or guess how much fluid I put in as there’s no gauge on the tumbler wall
Great that they let you purchase seperate. As I accidentally dropped my lid!
1. Because of the capsule shape, its very unstable. Keeps on falling over. If you are someone who keeps on drinking small sips over a longer period, goodluck with spills.
2. The sip lock is very tight and very inconvinient to use, when trying to lock light.
