Checked with my Ampere-meter, there seems to be no difference in amperes. I thought so many people bought it and gave positive ratings so might as well try, but it's fake.

They fit perfectly in the straw hole and actually prevent leaking. My only problem is how flexible they are since they are silicone, and when you hit the bottom of the tumbler it bends so you have to be careful. I love how they can be bendy if you need them as they are so flexible when drinking. Love the colours and I like them so much better than the straw that came with the tumbler.

I only needed 1 straw but now I'm so happy that I have a set!! The colors are bright & happy. I've been wanting a silicone large straw for my 44oz tumbler because I made the mistake of getting a metal one. The silicone is nice because if my elbow hits it while my tumbler is sitting in the cup holder of my car, it doesn't hurt or jab ha ha My 4yo won't cut his lip or bump his mouth while drinking out of it - or me ha ha The set came with 2 cleaning brushes, which is awesome! The brushes fit pretty tight but I haven't used them yet when the straws are wet so maybe that will make a difference. I'm just all around happy about these straws! I can use them with soda, juice or even water with my essential oils! Love them!

Oversized straws for my giant bubba mug. Clean up nicely on the dishwasher.

So happy with these, I bought them to fit my 40oz Stanley because I don't like the hard plastic straw it comes with and they are better than I expected. The colours are so pretty and they are the perfect size! No plastic taste. I also like that I don't need a straw topper, I can just fold the top into the mug and seal it, popping it out as needed. Have ran them through the dishwasher, (we have steam dry not an element) and they’re durable. 10/10 would recommend! Wish they came in more colours, pastels, I would buy more!

I have only had these for a short time, but so far, these straws are perfect for my 32 oz water bottles - and since they are flexible, I can put the lid in the bottle when I need to and they pop back up when I take the lid off!
