Love this water bottle! It is highly durable and I love that it is bio-compatible pure grade titanium. For reference, that is the level of quality that is safe to put inside your body, for say a hip replacement.
I can confirm that the lid does make noise when you screw it on or off, but I mostly leave the lid off throughout the day unless I'm out doing something outdoorsy. It's a very minor complaint, in my opinion.
My backstory has been water quality for the last 2 years. I have been highly concerned with the microplastics, fluoride, and general poor quality of the water supply locally. So much so, that I invested in a reverse osmosis system for my house. However, I realized that the water bottles I drink from daily are either plastic or low quality stainless steel, and this can contaminate my water.
This led me to Vargo (local Pennsylvania company) that is strong enough for outdoor activities, but also bio-compatible to not leak nasty chemicals into my drinking water.
My only change would be that I would ideally like the water bottle to not be made in China. I would hope Vargo regularly checks on the factory making the water bottles. I was hoping for a more regulated country that would ensure high standards of production.
