Brentwood GeoJug Stainless Vacuum Insulated Review

I already had a 32oz pitcher and decided to add two 40oz pitchers to my collection. My original 32 oz is doing up well after 2 years. BUT the new 40oz is only 8 months old and out of service. It is cute on the outside and no longer holds back the cold. It has not been dropped or put in the dishwasher. I tried to find out if they have a guarantee but to no avail. I bought two of the 40 oz and am hoping the other will last more than 8 months.
