Lifefactory 8-Ounce Stainless-Steel Vacuum-Insulated Wide-Neck Baby Bottle with Stage 2 Nipple (3-6 Months) Denim, LS2211WDE4

Love this for an insulated on the go baby cup. It keeps water cold which is nice for warm weather. I haven’t had any issues with leaking.

Was wider than expected, but it makes it that much easier to clean. Comes apart simply and easily in just three pieces. It passed the leak test, it’s also dropped on the ground a couple times so the rubber casing works well for protection. My nine month old is learning to use it and it is too heavy for her to lift on her own. I wish it came with more sippy attachments they do not offer them for this bottle without buying a whole new bottle. I was looking for a non-toxic drink cup to start fluids and I believe this will last throughout her baby phase into her toddler years as you can transition the lids. I am pleased with the quality.

My 2yr old loves this cup. Only use it for water, keeps it cold for hrs

Very good quality, my baby likes drinking from it. Sometimes it leaks - you have to be good at aligning the threading.

Okay, who tested this product and gave it the okay? I was recommended it on some one-off site, they probably got paid to recommend it.Problem 1: There is a teeeny tinyyy silicone hole stopper that prevents leaks, however, one swipe of the sponge and that thing was GONE down the drain. Now I'm left with a leaky bottle and a toddler who thinks it's hilarious to tip it upside down when I'm not looking, necessitating multiple outfit changes.Problem 2: The straw doesn't go all the way back! This causes bubbles to form and a gurgling sound – super annoying for baby and ME! I have to manually push it back hard to get it to stay for a few seconds...nahhh.Problem 3: The bottom of the cup has a weird metal sticker on it -- I don't want to pull it off for fear of exposing the solder that could be lead. It freaks me out.I just want this cup out of my life. And a REFUND would be great.

Time using it at the time of review: 7 monthsBaby age: 13 monthsBaby has been using this bottles since turning 6 months.Pros: the metal body is amazing: easy to clean, keeps liquids cold, no smells, super cute.Cons: THE STRAW CAP IS USELESS. Bad enough that I regret buying the bottle.1) The straw needs to be held back while baby drinks or you'll have only air coming out.2) If the straw is open and the bottle tilts or falls, all your liquid will be spilled FAST.3) Impossible to clean 100%There are many parts that can't be unassembled and are getting full of mold. I've tried toothpicks, tiny brushes, soaking, EVERYTHING and today I finally accepted I lost the battle to mold.7 months in I'm retiring this water bottle because of the cap, which is a shame because the body works really well. I'm bummed it didn't work and that I spent a good amount of money on a reputable brand that didn't live up to it's hype.Conclusion : stay away.

Great brand, really good quality. I got this cup for a great deal as well on sale and I’m very happy👍🏼

Insulation is great. We bought these to keep water warm for overnight bottles and they generally are warm for 3-4 hours. However, the nipple is NOT vented and there are ZERO MEASUREMENT MARKINGS. I have to weigh on a scale to fill with the right amount of water. Would not buy again and may replace with a bottle that has a vented nipple and ounce markings
