I've been using Voss bottles for years and have broken a few as a result of it being glass. I've always been a fan of wider mouthed bottles as it's easier to clean. Found this one for $5 so decided to buy a couple. Initially the silicon mouthpiece had a real plastic/rubber smell to it so I decided to soak it in detergent to hopefully counteract the smell. After soaking for a day, I put it back on the bottle and it still had the bad smell. I decided to take it out again, give it a good wash and air dry it for over 24 hours. I could still use the bottle without the silicon mouthpiece but there was a slight drip everytime you opened the bottle. After 24 hours, I put the mouthpiece back and there was no more smell. The drip was no longer present as well due to the seal it creates when you screw on the lid.
Overall, pretty happy with the bottle one week in as my bag no longer weighs an extra 700+ grams from the glass Voss. Time will tell how well it holds up with scratches and wear
