EcoVessel Bigfoot & Boss Triple-Insulated Bottles

Is there any type of warranty on these bottles? I purchased two of them and one of them isn't doing a good job of maintaining the water cold. Pouring ice and water in a cup and letting it sit last longer than pouring ice and water inside the 45 oz eco Vessel.

Amazon has the Mossy Oak for $30.79 with free shipping (even for non-Prime) which is two & a half bucks less than massdrop has it here with that obnoxious $8.25 shipping fee. They've got the larger one for $7.45 less than here if you don't mind blue - no free shipping until you kick it over the $49 level for non-Prime though.
