It's a way to get a VTS copy for a reasonable price. To be honest, it's not the same quality; but for a home gym, and if you take care of your equipment, you won't have any problems!
It allows you to have a Smith machine directly on the rack! It's quite sturdy and offers a wide range of exercises.
It should have four rollers instead of two, which would improve its sliding on the power rack.
It can also be used unilaterally with its handles, as well as with pulley systems.
It's a piece of equipment I use regularly in my workouts!
