Found the bottles on clearance but wanted the straw tops. Works well most of the time, occasionally can’t suck anything up through the straw but easily fixed just by opening and closing a few times. Wish they were a few bucks less expensive. Hopefully they’ll last a while.

Love the Lifefactory bottles. The straw is perfect for smoothies on the go.

We love our life factory bottles. The straw tops sometimes get a bit finicky, but they are still my favourite for my preschooler. We only use the straw tops with water to keep them easy to clean.

A bit pricey, but worth it considering the below.
We have gone through many bottles because of our 100lb large breed dog that can be a chewer at times. He got a hold of my DS LifeFactory bottle and would have destroyed it if it was any other make. The protective sleeve and bottle were completely unharmed, however, he managed to leave indents on the bottle top. We thought we'd be nice parents and replace the top with a fresh one even though there really wasn't anything else wrong with it. No leaks, super durable...little tough for small fingers to lift the nozzle but worth it considering everything else.

We love our Lifefactory bottles!!! My daughter wanted to try the straw cap and it has been working great for her.

I ordered two 350ml Lifefactory bottles within the past 12 months for my children. The seal of the first cap worked perfectly and was easily able to draw water up the straw to the spout. The seal of the second cap did not work, drawing only air into the spout rendering the water bottle useless. Upon receipt of the defective water bottle, I emailed a customer service representative from who sent a replacement water bottle and straw cap without hesitation – which was greatly appreciated! What is frustrating though is that over time the straw cap gets finicky and then eventually loses its seal – as now both of my straw caps do not work and cannot draw water up the straw to the spout. Now I have two useless water bottles. The glass Lifefactory bottle with the silicone sleeve is durable, washes easily and rates a 4.5/5. I have recommended this product several times, especially through, however the straw cap only gets a 1/5 from this disappointed mom.

Makes my original life factory bottle so much easier to use for yoga classes and work!

I love my lifefactory bottle but not the original drinking spout. This one is great and makes the bottle even more convenient.

Heather: more than a year ago

I love Lifefactory products and I was very excited to start using this straw cap with my bottle; however, it does leak a little and water squirts out at times from the spout when opening it. Overall, very convenient though!!

Love the straw caps! These are my favorite when driving so you can drink with one hand instead of trying to screw off the cap. And they are mostly leak proof, however, I still probably wouldn't throw it into my purse!!
