Review on Versatile EveryMile Aerobic Stepper With Adjustable Height - Non-Slip Workout Step Platform For Exercise, Fitness And Sports, Includes 4", 6" And 8" Risers For Full Body Training by David Alexander

only gave it 4 stars because it slides on solid surface floors. i put mine on my exercise mat and the problem is solved. the step arrived in perfect shape and i like the pink and black. the non-skid surface on the top is very nice. it has never indicated it was going to flip or pop up during a workout. the height ranges are really nice. I have a small exercise area downstairs and if this were any bigger, i would need a bigger workout area. takes a little getting used to making sure i step in the center of the top cause it's only about 11 inches wide - step moves should be done without your heel hanging off the edge.
