Before we go on please understand that I do believe this is a great exercise and that there is a place for it within our workout. The problem lies in the fact that nobody knows where this place is. Allow me to shed some light on the situation. This exercise does not only target the Biceps Brachii but due to the slight pronated grip at the wrist, the Bicep is forced to shar some load with the Brachialis and Brachioradialis which lies underneith.

The true biomechanical purpose of the Bicep Brachii is to supinate the wrist and this is why your bicep flexes when you rotate the wrist. Because there is no full rotation in this exercise and your wrists are forced to remain slightly pronated, the bicep cannot flx completely and therefor you lose 20% of the muscles ROM (range of motion) on every rep.
If you are all smart you would begin the bicep group workout with the Brachii and then move to the Brachialis and Brachioradialis with a more pronated grip last. My suggestion: Flat Bar into Rotating Dumbell into Eze-Bar into Hammer into Pronated Eze Bar.
