I received the Dual Wheel Ab Fitness Roller at a promotional price in exchange for my unbiased opinion. In the package was the 2 wheel ab roller that was very easy to put together as well as a knee pad to help with comfort while using the Ab Wheel Roller. The grips are padded and comfortable to hold. The 2 wheels help with stability. It rolls very smoothly without any issues. Its small enough to fit in a suitcase without any hassles to take along on your trips and still keep your exercise program going. It seems made well and not cheap but it is lightweight and sturdy.
