Great quality and very durable! Best on the market for sure! I love the focus on tracking the water consumption throughout the day it’s such an important message! I am always on the go and this bottle will now help me track how much water I am drinking! It really does encourage you to drink more! I also loved the leaflet in the box about the benefits of staying hydrated too! It’s easy to clean! I am going to take it everywhere with me to stay hydrated!
