Review on Sagler Glass Bottles 6 Pack 18oz - Includes 6 Sleeves (COLORS MAY VARY) - Glass Drinking Bottles for Beverage and Juice - Water Bottle Glass with Stainless Steel Caps - Leak-Proof Lid by Andrew Lyons

It's hit or miss I guess. One of my bottles cracked. But the rest seems fine. The glass is uneven. You can feel it in your hand when you hold it sleeveless. You can look at it and see that it's uneven on the inside too. But other than that it is as advertised. Nice and simple stainless steel lids that have not leaked before. Contains 6 sleeves of the same color. And he has a relatively comfortable mouth for drinking. I got all 6 bottles for ten dollars. I don't regret the purchase, but if I ever need to replace them I'd rather spend the extra money on a higher quality glass water bottle. **UPDATE** Almost two months later, the silicone seals in the bottle caps started falling out. It's been around for a few weeks, I'm in the process of updating this review. One of the caps does not close, it leaks and renders the bottle unusable. With 3 of the 5 bottles I left with the seals falling out I'm afraid they will become unusable at some point soon. I'm deducting a star and increasing my rating from 3 to 2.
