Bests & Worsts Reviews from Amazon

I fell in love with Bubba mugs while on a road trip through Yellowstone National Park with a friend a couple weeks ago. She had the car stocked with fun treats and we each had our own Bubba cup. After that weekend, when I flew home, I couldn’t wait to get my own. I bought one at Walmart and ordered 2 here on Amazon. I’m shocked and so disappointed that all 3 do not keep ice for more than 4 hours. How is this possible that all 3 have failed from 2 different stores??? I just ordered 2 off the Bubba website to compare but I fear they have changed something in the manufacturing process. I know these are normally amazing because I’ve experienced it! But, sadly, the love is gone.
