Love these bottles- My daughter drinks easily from them. The only recommendation is to ensure you've screwed the bottom and top on tightly to ensure it doesn't leak. Otherwise I find them easy to clean.

Really nice bottle. My daughter loves that she can drink quickly and hold the bottle on her own.
Downsides- ALWAYS drip water on me after I fill them or wash them and it's a lot to take a part to wash.

Great bottle. I have a few of them. Easy to clean. My daughter didnt have problems using them. They last a long time.

Love these bottles!!! My baby does not have gas after eating from these bottles. She really latches well to them. They are very easy to clean and I would recommend to everybody who is expecting a baby. Number one in my books for sure!

These are the best bottles and nipples I've found for feeding my baby. Because my boy has the most ferocious appetite, I've had to supplement with formula. We've tried many different bottles and found that the formula comes out too fast, causing him to choke or spit up aggressively. Keep in mind these all say they are slow flow nipples for newborns. The Playtex VentAire slow flow nipples are the only ones that work for him. Also the bottles themselves are designed to reduce gas and I find them quite effective at that compared to others. We have paid $20 for fancy Medela nipples (does not include bottle), that didn't work for him at all. These are about $6-$7 each and include the bottle.

You can reuse the bottles as he gets older by using the fast flow nipples, which you can purchase separately.

Overall great product.
