I ordered the 40oz bottle and instead received a 32oz bottle. I emailed customer service and they were kind enough to send me another bottle but unfortunately the second bottle was also a 32oz bottle. I'm not sure if they do not have 40oz bottles available or what the issue was but I ended up with 2 bottles and neither bottle is the correct size. The bottle itself is good with a couple of minor issues: 1- it will not keep your drink cold for 24 hours as advertised - at most it will remain cold for 8-12 hours depending on whether you are outside in the heat or inside with an air conditioner. 2- the cap has an air vent that has a little rubber insert which allows air in for the suction action but stop water from dripping out. The rubber insert came with no hole through it so I was unable to suck the water out of the bottle at the beginning. I then used a toothpick to make a hole through the rubber insert which allowed the water to be sucked through the straw, however, the suction action is not smooth. you have to suck hard to get the water through the straw. The bottle itself looks nice and the accessories (the rubber bumper and paracord handle) are great. However for the being sent the wrong bottle twice and the small issues with the bottle were a deal breaker for me. I will be returning the bottle. P.S. I had purchased a 40oz bottle from amazon (hydro cell) for $26 that performs much better than the frost buddy and is available in different sizes.
