Guitar Harmonizer Pedal Cheapest on Amazon! Amuzik DROP TUNE PITCH SHIFT HARMONIZER OCTAVE PEDAL

TC Electronic Sub n Up, Digitech Drop, Mooer Pitch Box alternative guitar pedal.
Cheapest Budget friendly DROP TUNE PITCH SHIFT HARMONISER/HARMONIZER OCTAVE PEDAL I could Find on Amazon or Ebay. The Amusic Harmonizer Pedal!

Does it pitch shift effectively and act as a drop tune in the same way as the pitch blocks in AXE fX, LINE 6 HELIX, Quad Cortex, Digitech Drop, TC Electronic Sub n Up and the Mooer Pitch Box? Maybe at a push even the Boss Octave pedal? Can it do the Van Halen Micro pitch shift effect?

In Many ways this pedal is more of a competitor to the budget friendly Mooer Pitch Box simply because of the budget friendly low price point or even cheap price of both of these pedals. But. Does it compete with the big boys? Is the tracking accurate, Does it sound good and what is the latency or lag like? Is it usable?
