TMB - Modular Bottle

great bottle main thing i would say is it would be nice is the mouthpiece could also be made of glass or maybe copper- something anti-microbial that's also not going to mold or add microplastics to the water. i would say the plastic mouthpiece is the only thing i would change

If these reviews allowed halves, this would be a 4.5* review. The bottle ingenerally great inwhat it allows you to do with one bottle and the glass insert is great! My only small gripes are that the lid doesn't unscrew in one piece so sometimes you have to realign the gasket and cap in the larger lid before putting the lid back on, which isn't a big deal except for the fact that this bottle is decently smaller than the old bottle I was used to and I have to refill it frequently.

I generallyreally like the bottle, my only small gripes are that the lid should have a construction that allows for removal of the lid without the top coming into pieces. It just makes refilling the kinda a pain, and since it's only 500 mL, I have to refill it quite a bit.
