Cap holds water
After several months of owning a 27oz bottle with this cap, I wondered why the beverage tasted funny, here when I put it in the sink to wash it, the cap would suck in soapy water. I ended up drilling some holes in the bottom and could not believe all the soapy water that came out. I will now stick with the drinkable caps at least I know nothing is going to spoil my beverage.

Stainless Caps retain fluid and RUST!
I oredered this cap as an alternate cap to use with the sport cap on my 40oz bottle. Both were ordered from Amazon.

First, the new SS caps are not the same design as the original (on a KK bottle I bought that came with SS flat cap 2 years ago) the knurled edges only go around a portion of the cap and they are not as high in relief, this makes the cap a bit harder to get off, this is just a nitpick. BUT...

The real problem with this cap is what others have mentioned, water leaks inside the cap (between the plastic and SS threaded portion. I read the reviews and decided in advance I would not submerge this new cap. I washed by hand, filled my bottle a left for work. When I got there, I noticed that some of the water I had put in the bottle was now stuck in the cap, I stress that this was liquid from my beverage (water). I don't feel this cap is safe to use, and completely unacceptable - if you fill your KK with different fluids, such as juice, do you really want this liquid staying in the cap to age/spoil and then possibly re-entering the bottle.

The SS flat caps (at least this version from amazon) are a waste of money. I can't say it is the caps fault, but I also noticed rust on the thread of both the bottle and cap - it could have occurred on either one and then transferred to the other so I can't tell which is to blame. Again this was on the first day of using the bottle and cap. My two other KK bottles, one with SS Flat cap (older design) and a newer one with PP loop cap both have never had any problems. KK needs a new design for the SS caps - I would not buy these until this issue has been fixed.

Do not submerge
I ordered these as replacements to the plastic lids that came with my kanteens. They came with a "Made in China" sticker on them, so I soaked them in the sink to get the stickers off. They wanted to float, so I had to put something on them to hold them down in the water. A couple of hours later (I got distracted!), I picked them up to scrape off the stickers, and what do I hear but sloshing water... the lids had taken in water, but there was no way to open them up and get it out. All I could think was that the soapy water would be slowly leaking into my drinking water. So... it was back to the plastic lids Klean Kanteen Loop Cap/Polypro for us! (BTW, HealthEGoods was very helpful about returning them).
