Rambler 40-Ounce Travel Straw Mug

I bought this water bottle about three months ago because it was advertised as leakproof, but unfortunately that hasn’t been my experience. At first it worked fine, but recently it started leaking. Now whenever I fill it with water, it slowly leaks out, which defeats the whole purpose of buying a leakproof bottle. It’s really frustrating because I expected it to last much longer than just a few months. The bottle itself looks nice and the size is good, but the leaking issue makes it unreliable to carry in a bag or backpack. I’m disappointed because I specifically chose this product to avoid spills. Overall, it might work well at the beginning, but in my case it didn’t stay leakproof for long. I hope the manufacturer improves the lid or sealing mechanism in the future.
