I have always loved the idea of the Avent system, because of the interchangeable sippy spouts. My kid is a biter; the spouts of his sippy cups invariably get badly scratched up and therefore need to be replaced. With most sippies this means replacing the whole cup, which gets expensive! The Avent system eliminates this problem; however, their sippy cups leak like mad (the lids unscrew WAY too easily) and the bottles are made from nasty leaching plastic. The Via system is #5 plastic but too clunky and cumbersome to use as a sippy.
The Klean Kanteen is the perfect solution: safe stainless steel and the convenience of interchangeable Avent sippy spouts. I was beyond thrilled when I learned that it existed.
The adapter cap has two pieces: the part that screws into the bottle, and then a piece that is EXACTLY like the white screw ring from an Avent bottle (except that it's black, of course, and just a little bit bigger). This means three things:
1. ANY Avent sippy spout or nipple will fit in it. Both the white and the green spouts are meant for babies first learning to use a sippy cup; this is probably why many toddlers get frustrated trying to drink from the spout that comes with this bottle. There is a "toddler" spout available that is much easier to drink from.
2. It will leak if you over-tighten it. DON'T screw it as tight as it will go or it will leak.
3. The Avent dome caps fit. (I am surprised that nobody seems to have noticed this before!)
(It seems like the Avent handles should fit, but they don't, or at least I can't seem to get them on quite right they cause pretty excessive leaking. It's a shame because that would make this cup absolutely perfect for younger toddlers. For my 2-year-old, though, it's just fine without handles.)
I plan on getting a neoprene cover for it to keep the contents cold (and because my son saw the one I have on MY Klean Kanteen and wants one for himself!) but other than that, this sippy is pretty much perfect. I love it!
I was SO excited about this product and ordered two. They both leak everywhere. Also, when I pour milk into it from the refrigerator, the kanteen is so cold that my toddler can't hold it. We had to cut up a sock and put it around the kanteen, which was actually fine if that were the only issue. When I first fill it and shake it around it doesn't leak. Then when my son drinks out of it and puts it down, milk spurts out from every possible place whether I tighten or loosen the top. I also bought a stainless steel straw cup by Thermos(which claims no BPAs in the straw parts). With the straw cup you know it will leak if it tips over, but at least it is totally leak proof if the top is closed.

I have 4 of these sippies and I find they are a wonderful investment.
With all the publicity about the leaching plastics I wanted an alternative to the plastic route, and the plastic ones we had were needing to be replaced after only a year, due to being dropped and cracking, or the area the valve fit into was cracked. I went looking for an alternative and found these. I started out with ordering 2 and now have 4 to rotate. The sippy spout that came with the first 2 was the Avent anti-spill soft spout and that seemed to work better than the hard Avent anti-spill spout on the 2nd set, My 2 year old initially didn't like the cold steel but the soda can cozies fit the bottles and work great.
I was having a hard time finding a bottle nipple my youngest would accept. From about 3 days old till 4 months he used the 5 oz Gerber Nuk Orthodontic bottle. After hearing the concerns about plastic, and him getting to where he was drinking 7oz at a time I needed to go up a size, but the slow flow nipples he was used to wouldn't fit, and the new ones were faster flow. I tried all sorts of nipples and bottles, when all of a sudden a light went on. The sippy 2 piece adaptor looked about the same size as his old 5oz bottles, sure enough the slow flow nipple fit in and works great. I just ordered some more Stainess steel bottles in the 18oz size for my 2 year old to work into and am going to look at these as a 20 year investment, they work for baby bottles, sippies, and down the road sports water bottles. :-)
They do leak a little if there is pressure in the cup through the vent hole, but it hasn't been enough to concern me, I think they are a great find.

I bought two of them for my kids and found out that the part inside the neck of the bottle is still made from plastic (which I wanted to get rid of as much as possible). Also, because you need to screw in the neck insert first, then you can put the cap on top of it, sometimes it just stuck together because the screw fastening part doesn't work very well, and I have to take both parts out and re-do it again. Frustrating.
Also the cups have leaking problem too.

I bought one of these for my 15 month old son and I LOVE it. I plan to get 3 or 4 more. It doesn't leak at all. I had expected some leaking because we have trouble with just about every sippy cup out there but not with this one. I had no troubles with the dishwasher either. I love that I can replace the tops and he can still use this later and not feel like a baby. Great product!
My little guy just loves this jar. He is almost 10 months and I am sad that we will be moving away from the 2nd foods and flavor combos. I am impressed with the line of antioxidant blends. I am happy with Amazon's "grocery" business. It is great to have the convenience to order these on-line and have home delivery. I can't imagine going the store and having to get a whole case and go through check out. I try to make him some meals, but I trust Earth's Best and love the flavor combo's and they are so convenient.
