Brieftons Borosilicate Glass Water Bottles 18 Oz, 6 Pack, Dishwasher Safe, Leakproof Stainless Steel Lids, Clear Glass Bottles with Lids for Juice, Smoothies, Kombucha, Reusable Beverage Containers

Pros: Health. Good hybrid product, to replace the commonly-used plastic bottle, combining the healthier benefits of glass with reduced breakability. Size. Very versatile size. Easily fits into most any vehicle cup holders, whether in console or door. Easy to grasp and easy to hold. Most similar products are far too wide, making them easier to drop. Visibility. The obvious transparent glass makes it easier to see the contents and the condition of them. Almost all plastic bottles have solid or patterned finishes. For example, I may want to know if the contents beginning to spoil, have they settled, do they need to be re-mixed, etc. Seal. I have had two of these bottles completely filled with water, laying flat on a bed for over two weeks now. Absolutely no sign of dripping or leakage. Very impressed with the gaskets that come in the lid. Cons: Description. I wish the product description and images would provide Fahrenheit readings in addition to the Celsius readings, for easier reference. Price. I think these are slightly over-priced at $22.99. IMO, $17.99 or $18.99 may be more on target here, for a bulk, 6-pack purchase. Drop Test. Although I have not tried to break this product, glass can of course break if hit or dropped hard enough. So I'm sure this is certainly not as resilient as plastic but still probably the best compromise due to the dangers of plastic.

These glass bottles are exactly what I was looking for. In my opinion, they are thick and high-quality. I haven’t dropped one, but I have accidentally banged it on the side of the door and it did not break. I can also verify they are actually borosilicate glass because I can pour boiling water into one to sanitize it and then turn around and pour cold water into it. I have never had the bottles leak on me so the seal is nice and strong. Every morning, I fill my six bottles with water and it helps me to meet my water goal because I know that I need to drink all of them by the end of the day. I actually do two bottles of regular water two bottles that have fiber mixed in and two bottles of an electrolyte mix.

These are great for alkaline water, they're nice and clear and so far have held up well.

Nice, sturdy glass bottles with a good weight but the mouth was too small for my purposes. They’d be great for juicing if you’re using a funnel to fill but I wanted them for protein drinks so they wouldn’t work well for filling with water from a jug and scoops of powder.

No issues at all borosilicate glass bottles came correctly packaged and in prestine condition ,beautiful bottles very fair pricing

I really like these bottles. They are such an upgrade from the plastic ones that I'd been using.

I am making the switch to glass away from plastic containers, and needed some bottles for water storage at work in my truck... these are what I decided upon. They feel like I could drop them and they would survive, but not willing to test that just to test it. There is a debate about recycling borosilicate glass.... etc. I plan to use these until they break, which I hope will be more than a decade from now. That will offset a mountain of plastic I have been using, much of which is being buried anyway, because the recycle system is struggling in the US. Between use LESS, or RECYCLE, using less reduces the total waste that has to be addressed anyway. While I would love if they were bigger, like 1 liter, at those sizes, you need to buy them individually. So I opted for smaller size but a set. Like a starter set for me... These feel sturdy in the hand, and the lid clearly seals the contents as the water tried to evaporate but condensed at the air gap at the top of the bottle. I will definitely need to watch them in the winter with ice expansion when they freeze, but I am happy with them for the summer so far. The mouth of the bottle is larger than typical water bottles, which is nice. I am hopeful they will perform well over time, and while I may ultimately switch to larger bottles, these work great for now. I plan to explore some juicing, so these may be converted from water storage to juice-to-go bottles at home in the future. Summary: Good Purchase, They Feel Solid!

Overall, these bottles are good and a great replacement for plastic bottles. They have a great seal and are leakproof, thanks to a silicone o-ring, though it's worth noting that silicone can also be associated with microplastics. The description advertises a stainless steel cap, which implies it's made entirely of steel. That's only partially true. The outside of the cap is metal, as is a piece of the inside center, but it's metal over plastic/plastic lining. I'm okay with this because I understand that not everything can be made without plastic, just don't exaggerate the description. Hence the 3 star rating. In terms of cost, I think the product is slightly over priced and should be between $15-$18.

The bottles looked bigger in the pic. Probably my mistake they I overestimated the size. Returned the item
