Shockingly poor quality
Purchased the same water bottle, one from Amazon and one from Ulula by Pura. These bottles are plastic free, made from stainless steel and the lid from "medical grade silicon".
The metal is shockingly low quality- the first one dented in the bottom and sides, I dropped it a couple of times and put it down to that (although my partner has a different metal bottle that has been dropped plenty of times and is still intact and undented), however I bought a second one and this one bowed in the bottom just like before within 1 day of use even though I hadn't dropped it at all.
Onto the "medical grade silicon" that goes mouldy and black within less than a week between deep cleaning it, and some of the black stuff never comes off even scraping at it, the inside of the silicon is stained a yellow-brown colour. I will add I have a GOPure water filter in the bottle at all times, so its not the water quality.
The quality of such an expensive bottle is shockingly bad, AVOID!
I have been in touch with Pura to inform them of their faulty design and not had any response at all.
