321 STRONG 500 mL (16.9 Fluid Ounce) Aluminum Water Bottle, Black, Silver, Red, White, or Blue

This water bottle has been used almost daily and made trips all over the world. Here is the good, bad and ok.Good: After two years it still hold ice very well. Sometimes I forget I put ice in there and a day or so later there are still ice chunks. So it really insulates VERY well. It has been dropped so many times and it has not broke yet. It has some dents but it is still very functional.Bad: The paint started to fleck about a year into it. Not a huge problem. My wife just scrubbed it with a metal scrub thing and it is now a shiny silver.Ok: It can be a bit of a pain to clean. I think its best to do it by hand. Not a real big problem since the top is a large opening.The plastic that attached the top to the bottle is very stiff and is starting to tear. I don't care about that too much but it may bug some of you.It's so big it doesn't fit real well on backpack sleeves and in cup holders (unless you do it upside down.) The top never leaks much unless you don't screw it on right. the only other thing I can think of that may bug some people is if you drink straight out of it, its such a big opening that you can sometimes spill a little if you go too fast. (My little nephew just thought it was the funniest thing to watch me [an adult] keep drinking out of it and dribbling water on myself.)So if you want a really big waterbottle that will keep you drink hot or cold for LONG periods of time then this is it.

I have had this bottle for about a week, and it is the best water bottle I have ever purchased. Overall, I think this is the best purchase you can make during the summer. In 80+ degree weather and unbearable humidity, all you can ask for is a water bottle that keeps water cool, and you hydrated for when you need it the most, and this bottle delivers 100%.During a hot day at the beach with friends, playing basketball, or hitting up the volleyball court, I leave this bottle out in the sun with no shade whatsoever for 4+ hours, and the water inside is still as cool as when I poured it. Can't say any longer than that because I usually finish my water within that time, but I would not doubt it keeps water cool for much longer.With it being said that it is the best water bottle I have ever purchased, it was also the most expensive. But I believe it was very well worth the price. I am certain this bottle will last me throughout the rest of the summer, and following summers after that. It is sturdy, easy to hold, and it has the perfect size opening (but that's because I personally hate bottles with narrow tops/openings). I definitely recommend buying this bottle. I haven't found any cons to this purchase.

As someone who works in law enforcement I never have access to a fridge to keep my stuff cold.Well this bottle is great for keeping you water cold. I can be on a 12 hour shift and the ice I put into the water in the morning is still there which is amazing. So I use this bottle to hold my cold drinking water and another bottle to hold a larger amount of water that isn't insulated.Great bottle. I like the feel and the rough finish on the outside for better grip.

I have had two hydro flask 40oz bottles and while the lid that comes with this bottle is nice I prefer the straw-lid combo I've had from past purchases and with this being a wide mouth bottle previous lives work with no issues whatsoever. I can say that after having this for several weeks this preforms just as good as the other guys at a fraction of the price. I'm a water fanatic, my everyday ritual is to fill the bottle half way with crushed ice... Fill the rest with water and throughout the day refill the the bottle with cold water. I probably do this cycle about 5 to 8 times a day and I still have crushed ice left over at the end of the night when I empty out the bottle. As you can see in the picture the inside is clean and bright, there are no blemishes on the inside which is where it really counts and no blemishes on the outside. Overall I feel that this was a great purchase and really good value for the cost. When I end up wanting a different color I'll definitely buy again from this seller.

It is the perfect size( size of a standard disposable water bottle) and the perfect weight. Also there is no metallic taste (like you sometimes get from other metal bottles) and it does not leak whatsoever.****update****Just the other day I had the bottle spill inside my bag and wet all my papers. I inspected the bottle and noticed that the threads within the bottle(not the cap) are no longer catching. I can twist and twist on the cap and it will no longer tighten. Because of this i am removing some stars from my original review.****new update****Contacted the company, they responded immediately to the issue. They gave me a few options which I was very pleased about. Because of this great treatment they have earned a revision.

Seems like a good quality product. A great deal of consumers dont realize that big brand names like hydroflask dont do their own manufacturing, its contracted out to a mass production facility that does private label and branding. This flask is probably made at the same place that hydrflask brand is made at, and id put this up against hydroflask anyday and say this one performs just as good at a fraction of the cost. Its a sturdy build and it has held my water at temperature i desired for a long time. Im moving away fromplastic, and this actually the second best thing next to glass. Since glass has a greater propensity to break, this is the choice. Its a good buy, id recommend it. No, it doesnt fit in a cupholder in a car, but it holds 40 ozs and maintains a constatnt temperature of the beverage.

I work outside in Southern California. Its warm a lot, its hot often. I stopped carrying an ice cooler around and started carrying these 321Strong vacuum bottles full of ice. #1 the ice doesn't melt even sitting in the sun 5-7 hours.. #2 even if theres a little melting the water stays very very cold.#3. They are easy to carry around. I work with teenagers and they don't exactly think about hydration in the hot sun. So I line up 3-40oz bottles full of ice and put a couple gal of water next to them .The system works great.
