I've been using the ORIGIN WIDEMOUTH glass bottle daily for a few weeks and it's held up well. The borosilicate glass feels solid and doesn't retain any flavors from my juice or protein shakes. The silicone sleeve gives good grip and protects against short drops, and the bamboo lid seals tightly with no leaks. I also like that it's dishwasher safe with the sleeve on — just hand wash the lid. The widemouth opening is easy to drink from and clean. Happy with this purchase.
