I purchased this machine to replace the Ab Circle Pro I already owned. The quality of finish is incomparably better so is standard of the material. The welding of the parts looks very clean and so shows much higher professional workmanship has been put into the assembly of the machine. The steel tubes are much more wider and feels more robust than the AB Circle Pro and so provides more confidence in the use of the machine in terms of safety.
The kneeling arms are faultless and symmetrical and the knee pads are more ergonomic and therefore feels more comfortable. The computer does what it is supposed to do and that is to keep the count of the repetitions. The AB Motion Xtreme is a more aesthetically pleasing looking item. It took me a lot of effort to keep the old device working including purchase of new rollers. The new Ab Motion Xtreme is a better proposition than the previous so called 'professional' AB exerciser. It is a much more quieter machine especially as it does not use rollers which is the main cause of noise from the original machine.
Very pleased with the Xtreme and would definately recommend this product to anyone who wants to work on their abs
