Review on Trailblazer Vacuum Insulated Stainless Bottle Licorice by Elizabeth Morrison

After a few weeks of use I noticed that rust was forming on the inside of the bottom of the mug. At first I thought it might be dried coffee, but I started looking closely and noticed that it was actually rust spots. I no longer use a mug due to concerns that drinking beverages, hot or cold, can cause health problems. I don't think it happens to all cups, maybe just mine.
