yakkowarner's Full Review: Klean Kanteen Stainless Steel Water Bottle (27oz)
I got this version and a 40 oz version from REI for a good chunk of change because of my concern of BPA (Bisphenol A.) The bottle is 18/8 stainless steel construction with a medium sized cap large enough for regular ice cubes to fit. It also has a plastic cap on top that screws in securely with a rubber ring so it will not leak. The plastic top is made of #5 plastic that does not have BPA in it.
I think I need to clarify that the whole bottle (inside and out) is made from stainless steel. Some, like this model, have a painted exterior. This one is pitch black, my favorite color. They also have recently put out a sweet looking red.
Why did I buy this and what phobia have I developed I remember the parents of a past friend telling me about transfats and that margarine was actually a plastic like substance. And they told me it was responsible for the increase in heart related deaths over the past few decades. I thought they were a little crazy and I just nodded and smiled. But guess what, back in 1994 they were right. And now all of the fast food changes and many other restaurants have taken trans-fats out of their kitchen.
Now as a parent I've gone off the deep end with them in my growing phobia of the foods we eat and products we use. Now I'm reading about BPA being a problem in our food supply and that combined with the artificial dyes are going to cause abnormalities in our children's development. Over the past month I've researched and looked through my cabinets to see what I had. I have since gotten rid or all #3 plastics and don't use #6 plastics. I use #1's once.
From what I have read, it is only #1, #3, #6, and some #7 recyclable products that you need to worry about. My in-laws doctor said it is everything but #7, but from articles I read I don't believe that to be true. I read somewhere that reheating #1 & #6 with water inside can cause leaching of chemicals but some other articles disagree. I have an REI mug made out of #7 plastic but they are adamant on their website that the mug is BPA free, but I have been drinking out of ceramics for the most part now. I don't think a clear verdict is out yet nor will one come soon without good research being done (and I don't think enough research has been done on everything in our food supply in general.) But I needed a solution and since I haven't seen a clear consensus I have chosen to avoid using Lexan for the time being. This left me with no real choice other than to get stainless steel for water and trust the REI website when and if I get a #7.
So the fear that I have is not completely founded but with the issues with trans-fats and the new research from food coloring additives, I felt it is best that I use the safest material around for both my family and myself, and get rid of any possible contaminate (that future research might find). This includes switching from refilling my plastic bottles (which are disposed of eventually) to using these stainless steel bottles. Yes the cost is more initially but the stainless steel should last a good decade or more. I also will be putting less plastic in the recycling bin at home (or the trash bin at work).
Here is what was written in the supplied documentation. “Recent studies have shown that many plastic water bottles, including Lexan bottles, leach toxins such as Bisphenol A (BPA). These studies have linked BPA to breast cancer and reproductive mutations.” I don't know their source but as I mentioned there is a lots of different opinions on the subject if you research it online. I've given some other sources at the bottom.
Main features This is a stainless steel water bottle. Stainless steel is great because it doesn't leach any flavors, can handle acidic substances (aluminum can't), is easy to clean, can handle dishwashers, and takes my abuse.
Materials 18/8 Stainless steel. This means it has approximately 18% chromium and 8% nickel. This means it is non-magnetic and is more corrosive resistant than metal with less nickel (source:http://www.ssina.com/faq/index.html#2). The top is plastic #5. What I have read is that #5 does not have BPA in it, although I probably will get the stainless steel tops next time I'm at REI. And remember, just because a bottle says stainless steel does not mean the interior is stainless steel (my Gevalia containers I got are plastic in the inside.) Thankfully the two 1 liter bottles are made of stainless steel inside and out.
Ergonomics and ease of use. When comparing this to the 40 ounce, I think this is the perfect size. It fits in my Avalanche cup holders well (but not perfectly, whereas the 40 oz does not fit in the cup holders at all.) It is easy to grasp even if you have small hands. Easy to drink out of. I do not find my hands slipping when I take off the lid. My only criticism is I would like a bigger top so I can screw off the top more easily (I have found that the wide-mouth 40 oz bottle is easier to unscrew than this one.) But both are well balanced and have just the right foot print to keep it from falling over easily.
Who is this for? Anyone that wants a durable leech proof bottle and doesn't mind a little weight. For backpackers I can't recommend this as a viable method due to the weight.
Cleaning I only use water so I just occasionally clean it out with tap water. If you use coffee make sure you get an insulated sleeve (which I have not bought yet so I don't know how well it works) and a bottle brush to get out the coffee residue that builds up.
Durability Good so far. I have had some black paint coming off and a small dent like 1mm deep (it is so small I have no way of measuring it.) And the only reason I saw it was I was in direct sunlight looking for reflections. In a dark room I would never be able to find it. And I can barely feel it.
Now for the fun!!! I banged it against my wooden desk (which is literally falling apart). It produced the same small insignificant dents. This is actually a good thing, because it means this will not shatter. I also banged and dropped it on the plastic head half a dozen times and I saw no visible marks on it. It can scratch easily. I hit it hard on the bottom with a screwdriver and there was no real damage. I can easily scratch the paint with the screwdriver head.
This is a well made product that should last me a lifetime. I'm sure I'll lose it before it fails. The only complaint is the paint is not as durable as I would like, so from this point on I will probably only buy the non-painted versions.
What I like. -Dishwasher safe. -Rugged. -Easy to drink out of. -Easy to hold. -Does not leak
What I do not like. -The weight.
What doesn't matter: The scratches, everything of mine gets beat up and this can handle 3 foot falls with no problem. I like my bottles too much so I'm not going to see how much of a dent I can get from a baseball bat.
Weight and dimensions Weight (dry): 7 3/8 ounces Diameter on the bottom (approximately): 2 3/4 inches Height: 10 3/4 inches Capacity: I filled mine to where the screw marks start and I got just over 27 ounces.
