Review on 🍶 BUZIO 32oz, 40oz, 64oz, 87oz Insulated Water Bottle with Straw Lid and Flex Cap - Modern Double Vacuum Stainless Steel Water Flask, Long-lasting Cold (48 Hrs) & Hot (24 Hrs) Thermo Canteen Mug, BPA-Free by Jason Camarillo

So I received this 64 oz bottle at 10:40 am on Friday and wanted to "test" how well it works while staying cold. Let me tell you I was speechless with the results! We live in Florida and it was 90+ during the day and 105-110 in my black car. So after it was half filled with ice (no water), the lid closed and the outer carry case put on, it was thrown in the car. Below are my findings. 13:00 - as if nothing had melted. 15:00 - maybe an ounce of water (108 degrees in the car) 18:00 - about the same amount of meltwater. Saturday, 9:00 a.m. - About 2-3 ounces of water. - enough water for 4 sips of ICE COLD Sunday 9am - about 1/4 filled with ice noon - about 3 ounces of water (110 degrees in the car) 6pm - drank the rest of the water and brought the bottle home. 7:00pm - Dinner finished and attached photo taken. Monday 7am - I filled it completely with ice at work and filled it with cold water. ***Drank 3 times at 5:30pm and refilled with water, left work, no more water but still plenty of ice. (Left in car overnight - 82 degrees outside) Tuesday 7am - cold water poured in ***Drink 4 times and refilled (yes I drink a lot of water) 6pm - very cold water ready when I got home, 6pm: 10 - put the bottle on the table and opened the lid. It STILL had about 1 cup of ice on the bottom! If any of this sounds like what you are looking for, just stop reading and buy it now! Don't let the price fool you, it's worth it! I have already placed 2 more orders. (a 40 oz for the wife and 32 oz for the daughter's birthday) I'm sure I will be buying more as gifts for friends and family. This is easily the best water bottle I've ever had!
