This cube puzzle is a flash back to my youth when the craze was going on with the rubics cube. Now adays, everyone is calling them stress reducers because our society has put that much stress on us that we need something in our hands to help relieve the stress. I use this for my agents going into training taking calls for the first time to help them focus on their job at task. It helps them to stay focused and relaxed to be able to help our customers and feel confident in the job they are doing. Weather your looking for a stress reducer or wanting to introduce your child to a piece of your past this cube puzzle would be the one. It moves smoothly and freely like it should and isn't hard to turn or sticks when turning different directions.
