KEEPTO 1 Gallon Motivational Water Bottle with Straw, BPA Free Large Water Jug with Time Marker - Ideal for Gym, Hiking, and Daily Hydration

I love this water bottle and take it everywhere. People always ask where I got it. I accidentally broke my first one and immediately bought another.I like keeping these kinds of large water bottles/jugs around, and keep them on rotation (while a couple are cooling in the fridge, I'm actively working on another.) These are overall pretty decent quality with one rather significant design flaw that affects performance. The tube or "straw" that runs from the lid into the bottle runs very nearly to the bottom of the container, with only maybe a millimeter between the end of the straw and the bottom. Basic physics says when you start to impede the flow of a liquid, you build a high pressure differential. To dispense with all the science mumbo-jumbo, it's hard to suck things out of these bottles. I got two with a recent order, and had the same problem with both.At first I thought the hole in the lid just under the mouthpiece which draws in air from outside when you suck was too narrow. But that didn't seem to make as much difference when I carefully widened that hole. It then occurred to me to check the length of the straw. Sure enough, it was practically sitting on the bottom of the bottle.What I did was very carefully took a sharp blade and cut a small (2-3mm) "wedge" from one side of the bottom end of the straw. It's a fairly narrow cut, only about 15° or so, but it was sufficient. I put it back together and tried it out, and voila! That did it! A huge and noticeable improvement over the original. I tried the two side-by-side, and there was definitely a difference in performance. I did the same modification to the second bottle's straw, and they both work so much better now.My advice to the manufacturer of this product: either cut the straw's length about 2mm shorter than you currently are, or consider cutting the bottom end at an angle to prevent this issue. It's otherwise a good product, and this issue and the rather dodgy latch on the flip-lid kept it from being a 5-star review. I haven't tried a home fix on the lid yet, although I suspect some very careful minor filing of the two "teeth" that catch the latch might do the trick.The water bottle was for a student that had one for 3 years and then she dropped it. It was a replacement, excellent bottleI love the size of the bottle and the ability to pick-up and move around. Initially, the straw seemed stopped up. I gave it a twist and slight pull and it worked fine for about 1 month. When I cleaned it with the brush that came with it, then it felt like there was a hole in it. I looked under the lid and saw in-fact, the straw had a hole in it. Now I'm looking for a replacement straw or a separate gulp lid to prevent having to purchase a new bottle assembly.Love the bottle, love the comments on the bottle and time frames. Helps me to keep going. Only issue is when you drink from it as it gets lower you have to loosen lid so the air can get in if you try and drink fast. Otherwise it is hard to drink from.Super easy to drink from, a thin, long straw that fulfilled the needed requirements. It has a nice sturdy carry handle, as well as a strap. The lid is secure, yet not too difficult to remove when needing to refill.Would recommend to anyone.I’m a big water drinker and I love that it can hold a lot of water ! And it’s super cute.Only problem is as you are pressing button to open, the top gets stuck. I also tried double pressing which sometimes works.It works!
