Playtex Ventaire Advanced Wide Baby Bottle Review

I am torn on the Playtex VentAire Advanced bottles.  I really like that the shape of the nipple is similar to that of a mother who is nursing, so it is excellent to use for mom's who pump or switch from nursing to formula.  I also love the angled shape.  It makes bottle-feeding much more comfortable for the baby.  This is the only reason I buy these bottles because there are some other aspects of this bottle that are very frustrating to me.  One of those is that the measurement readings on the side that show how many ounces of fluid are in the bottle rub off, so be careful when handling and washing so that they print will last a little longer.  Also, when you screw the ring that holds the nipple onto the top of the bottle, you have to do it just so.  It doesn't settle on its own into the right thread.  The best thing to do is to twist it backwards until it settles in the correct thread and then twist it forward to tighten.  Another slightly frustrating thing is that I have bought 2 packs of these and one set of caps is too loose on the other, so I'm always having to find the "right" cap even though they should all be the same.  And finally, don't forget the little ring that goes into the bottom of the bottle... if you do, you'll only do it once... it makes a big mess!  LOL!
