The Evenflo Elan isn't a bottle you hear too much about and it's a shame because it's a really good bottle. I previously owned the Avent bottles and honestly, they grossed me out. I used a bottle brush to try and get to the bottom and around the edge and it was very challenging. There would be a milky white film around the inside. With the Elan, you can actually take the bottom off as easy as you take the top off! No other bottle that I know of does that. You unscrew the top, unscrew the bottom and then shove the brush inside and are able to get to ever place within. No old milk leftover and no pasty residue. Great to take apart and shove in the dishwasher for a more thorough cleaning.
The bottles are also airfree and that was noticeably better as well when I began using these. They also adapt to the breastfeeding system byu Evenflo Elan as well.
They come in Blue, Yellow and, Orange. These are really awesome bottles however Evenflo could improve the look a bit even though the colors are nice and vibrant rather than pastel like all the others.
