Review on 🧪 ATD Tools 1106 Premium Antifreeze and Coolant Tester by Shah Jones

2 floating disks tuck into the end cap of the tester. They didn't even move with repeated attempts to fill it with water and tap on it. Finally, remove the rubber ball to access the open end. Managed to knock the slices out through the hole. Thought it would solve the problem but no. Each time the slices were at that end of the product, they fell back into place. The item is defective and I wasted my money and time on it. I am disappointed in this purchase and would not recommend anyone to buy it. Bought a replacement from local NAPA, it worked.
