Hard to read markings, expensive, weird twist shape, nipple doesn't vent
Always loved the classic Evenflo glass bottle but his new tinted bottle gives the milk a really weird color and makes it hard to see the markings. The new twisted shape has put the ounce markings on an angle that has the numbers in between the lines; very hard to read. The pro flow nipple vents less than half the time. The new shape ring does not interchange with the old rings and caps. Wasteful. Not a fan!
