The bottles are too thin to be even slightly resistant to folding upTheir center of gravity too high to remain uprightTheir lids too thin and too sharp edged to hold form, and good luck not cutting yourself over extended useTheir walls too thin. These will perspire as much as anything, and because of the massive surface area, will quickly become room temperatureIf convenience and utility and re-usability are what you’re after, steer well clear.This isn’t a product it’s a cash grabIf water is what you’re after, you don’t need to spend money on useless aluminum cans that won’t make it intact thru the first refill.I think this is a great concept. I'm always a bit absent minded, so I often forget to bring a water bottle with me places. I use a Brita water bottle with a filter in it when I do remember, because I like the taste of the water the Brita filter provides. This feels like I get the same great, clean flavor in a bottled form. I throw one of these bottles in my car, gym bag, and keep one in my office at work so any day I forget my bottle I have one of these handy. When I finish it off, instead of just tossing it I can refill it from the sink or water cooler instead of wasting a plastic bottle. At the end of the day, it's great tasting water from a recyclable aluminum bottle. I'd definitely recommend this.*Edited*Don't buy. Product stated that these are reusable. I only had this for a little bit over a month and there's an awful taste and smell coming from the cap. Today is the third I noticed these black stuff from the lid.If you buy this product with an intention to reuse them, don't even bother. After opening the lid, you will have a hard time closing then. I bought these bottles so I can bring them in the gym but whenever I put it inside my bag, they always spill water because the lid are broken. If you close it tight, you will have a hard time opening then and will cut yourself because lids are made of metalTaste great. We can reuse bottles multi times.Will purchase againWe got these and immediately stuck them in the fridge so we could enjoy them cold. They are great. Tall water bottles holding a great amount of water that tastes just as good as any Brita drinker expects. We’ve also reused the water bottles a few times. They hold up much better than a plastic bottle.Love it! Great tasting and sustainably made! Perfect to toss in the car or pack in my sons lacrosse game for practice and not worry if it gets lost or forgotten. Plus the water is clean and crisp, and thanks to the aluminum, stays nice and cool. We even wash the empties so we can refill for next time. A busy, eco-friendly family must have!Unlike other aluminum bottle water, this bottle is stronger and doesn't have a plastic cap (BPA Free!). After drinking this great tasting water, I use my Brita pitcher to refill and reuse the bottle. Great sustainable bottled water.Save money, and save the environment! Waterboy approved. :)Loved these water bottles! They keep the water cold for longer than any other water I’ve ever had, great for a long strength training session! The water also tastes great. Definitely recommend
