5.0 out of 5 stars most problems can be solved with Avent accessories..., March 10, 2008

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!

1.0 out of 5 stars messy..., December 30, 2007

We bought 6 of these cups to get away from the leaching problems with the plastic cups. While these cups are ok with the sports cap or any of the other lids, they are horrible as a sippy cup. Milk leaks from the vent hole in fairly large quantities, which makes them useless as a sippy cup.

5.0 out of 5 stars We all love these sippies, July 30, 2007

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.
