DanForce 12-24 oz Stainless Steel Sports Water Bottle - Double Walled Metal Vacuum Insulated, BPA and Toxic Free. Keep 24 Hours Hot, 36 Hours Cold, with Leak Proof Straw, Sports and Cap lids.

I was very excited for these given the claims, and the price was great, but I’m just not impressed. I have several problems with these.1. The lid. The mouth of the bottle is smaller, but it did look big enough to fit ice so I got them. I knew it wasn’t a wide mouth. But the straw lid just doesn’t work well for this size mouth. I often times find myself bonking my nose on the handle since the straw does not stand that far up given the diameter. I almost have to remember to go in at a certain angle so I don’t bump my nose. The straw lid was the one I was going to use so I was bummed about this. My husband uses the screw on lid so this didn’t affect him at all.2. The manufacturing of the straw lid still has some room for improvement. I was going to use both straw lids from mine and my husband’s bottles, but one of them I couldn’t get the straw in. The hole that was machined on one was not a nice circle. So I had to take a knife to widen it more to fit in the straw. Then upon trying them both out, one cap has a valve that doesn’t work. This valve is meant to be closed when tipping it upside down so nothing leaks, but opens when you sip so air can get in and you don’t create a vacuum. Well one doesn’t work, so I can only sip just a little water out before a vacuum forms and I can no longer get anymore water out. Then I have to stop so the air can rush in and I can start drinking again. Very time consuming and annoying to just get a drink of water. I had to discard that one. Also, the straw opening has plastic that didn’t get cut off all the way so I had to scrape around the inside with a knife to get the plastic out. I shouldn’t be having to reshape holes and cut plastic out of the way. These are things quality control should catch. But I guess you get what you pay for. These are much less expensive than other bottles.3. The mouth of the bottle is not a wide opening as I mentioned before, and I knew this when I bought them. A small/regular size ice cube will fit, which is great. But one day my daughter over-filled the ice cubes and I could no longer fit the ice cubes in! Frustrating.4. I live in Las Vegas where we are over 100 degrees almost every day in the summer. Based on their claims, I was very excited for these! BUT THE LENGTH OF TIME IT WILL KEEP THINGS COLD IS NOT ACCURATE AS ADVERTISED! I may have given 3-4 stars given the other problems if it did. I filled up my water bottle with cold water from my water dispenser and added ice cubes. I took a test drink and indeed it was obviously ice cold. I sealed it, set it on the counter in my home- ambient temp maybe 73 degrees- and started timing. This was at 11:00am. At 4:00 pm I shook it and the ice was already melted!! I took a test drink and it was still ice cold. Nice. At 7:00pm I took a test drink and was only cool/cold. Not even as cold as if I had gotten a glass of water from the cold spigot on my water cooler. At 10:00pm I took a test drink and it was only cool-ish, more approaching room temp. At 7:00am the next morning I took a test drink and it was room temp. So these bottles do not keep water cold for 24 hours at room temp. Bummer. Granted I drink more than 21 oz in 24 hours so I don’t think this will be an issue, but I am not happy the ice melted so quickly. I don’t really have high hopes these bottles will keep my water cold outside in 100+ temps for more than a couple hours. I read a review from someone also from Las Vegas and they seemed happy. So I will have to wait until next summer to test this outside and TIME how long it takes to become warm.5. The handle on the straw lid isn’t that comfortable. The design or mould could have been better. The edge on the inside of the handle is sharp, not nice and rounded like the outside edge. Almost like those two pieces meet there so there is a thin sharp line of plastic. After carrying around a full bottle of water I get red marks on my fingers from the sharp line of plastic digging in.Overall my husband is happy with his. He drinks maybe 4 bottles a day so his water is always cold and he uses the screw lid so the straw is not an issue for him.*On to the good things:I do like the shape, size and texture of the bottle. It fits in my cup holder in my car which is something I was looking for and is a huge plus! I like that it doesn’t sweat. And I like the textured finish so it won’t slip out of your hand easily. I like that it comes with extra gaskets. Eventually they fall out and then your bottle leaks. So I like that I have some replacements. I do like that there are multiple lids to choose from. I had originally wanted to use the straw lid. But I switched to the screw lid because the straw was just too short to use comfortably.

They have good customer service, I had a problem with my order. The first bottle I ordered didn't hold the temperatures long. I LOVE cold water, and I have some near me at all times even at work. So it bothered me that this bottle only held the cold for about 6hrs over night. I wake up to drink water at night so I want it to be cold when I'm ready to drink my water. Now I put this bottle up against a 711 water bottle that I paid 10 dollars for to do the same thing so natural I was concerned, I paid more for the Dan Force product so I expected it to work. I contacted their customer service about my concern and the sent another bottle out to me right away. The new bottle worked perfectly honestly out performing the 711 bottle. So I really appreciated their product and their customer service skills!!!

I never write reviews but for this one I had to. This water bottle exceeded my expectations! For starters, they send you a customer service email after your item ships (with a coupon!), which I thought was above and beyond. I also love that even at a low price it comes with 3 lids and a straw attachment. But what's most important....the water bottle works! When the bottle tipped over water didn't leak out. It kept my water cold through 60 minutes of hot yoga and after. The bottle was actually hot to the touch on the outside while the water was cold on the inside...amazing! So glad I didn't overpay for a hydroflask--this works just as well with more features for a fraction of the price. Next time I need a water bottle I'm coming here.

Purchased 2 of the 24oz bottles mainly to use on the golf course and in the car. First of all, after unpacking I fill one bottle half with cold water and added six ice cubes then let it sit over night till morning at which time I checked it to find that the ice cubes had melted and the water was not COLD. I have used a bottle a few times on the golf course, with ice added, and at the turn the liquid was cool. I usually freeze my drinks and let them defrost as the game proceeds providing me with very cold liquid for 18 holes, this dose not compare. Also, these bottles Do Not fit in the holders in either golf carts or automobiles, you have to lay them down somewhere. Would like too have given 5 stars, but they do not keep liquid cold for 24-36 hrs and Don't fit in cup holders. It is nice to have three different tops and 24oz.

This review is regarding the claim that it keeps hot liquids Hot up to 12 hours- it doesn’t. I bought it with the intention to replace my 16 ounce thermos -however At most, It keeps my coffee warm for about four hours even after pre-reheating the bottle with boiling water for at least five minutes . It doesn’t measure up to my thermos 16 ounces which so far has no rival in heat retention. When compared side-by-side -I filled both of them with boiling water - nine hours later when measuring the temperature this bottle was at 140° and the thermos was 170.

The 24oz DanForce bottle I bought is excellent quality and fits perfectly in my cars cup holder. The fact that it includes 3 types of lids makes it an excellent value. I prefer the straw lid when I drive so I’m not tipping a cup up and blocking my view of the road.I use much less ice because it keeps beverages very cold for quite a while. And make sure your carefully test a hot beverage before taking a big drink as it does stay hot.About the only thing to not like is that although it says it is a wide mouth bottle, and it is compared to many, it is not as wide as others. But that may not be a big deal to you.Don’t hesitate to buy this bottle.
