Review on 🥶 Frosty Double Freezer Ice Mugs by Tom Duncan

Ideal for keeping your drink cold on a hot day. I don't have long experience with this particular brand but experience with others shows that they have a life expectancy of 1-2 years with frequent use. The constant freeze-thaw cycle leads to cracking or delamination of the floor. Well, they're pretty cheap, so throw them out and buy another set!
