Great water bottle. I don't know how I went through life without these

So let me start by saying I love this water bottle. I've had it for a few months now and here are my pros and cons. Pros : - Insulation is insanely good. This will keep a drink with ice in it cool for days left outside; or at least pretty cool. I leave this in my car with water and forget about it until its empty. If you left just ice in this and let it sit in your house, it would stay fine for days and cool for probably at least a week. -Visually very pretty & works as intended. Cons : - Drinking from this thing is a workout if it's full. It sucks that you have to physically lift it up to use. A long straw attachment for something this heavy or a handle on the side of the water bottle would go a long way because this thing is A TANK. - This will not fit in pretty much any cupholder ever made without some sort of adapter which is an expensive accessory I just haven't invested in because this was already like $30+ on its own. Neutral : Washing something of this configuration will always be a little challenging. Carrying this much water around will always be heavy to both transport but especially to drink. If your priority is keeping your drink cold, this will do it with flying colors.

Just what I wanted. A bottle that will last my whole shift (and then some.) Good choice. No plastic and insulated. Works for me!

This flask as it’s called is huge,my teenage sun loves it!Hes autistic and doesn’t like drinking out of a regular straw,cup,or bottled water top.So im upgrading his mug he’s had a few years just because he’s becoming a lot more flare savvy,and the other one just served it’s purpose.This comes with an extra sleeve that comes on the bottle easily taken off,2 straws that fit on the end of the top.A straw washer,well everything it says.I literally just got it and came straight to write a review he loves it,and I’m equally impressed.
