This is the coolest device. You can literally fill a hot coffee up to the rim, go up & down stairs; swing the carrier back & forth, and the cup doesn’t budge from the center of the carrier. I love having clean, no coffee stained carpets.
The Rocking T Knife is an awesome tool for people who have limited hand function, tremors and/or a weak grasp. The reviews are stellar on this kitchen tool that will prevent a trip to the ER.
