Pros: Two speed options are a plus. You can turn the depth down and use this as a clean boost. Internal switch available to offer an additional level of speed control. Smooth tremolo overall.
Cons: There is no internal 9V battery option, which would have been nice to try and isolate the power from my power brick to troubleshoot some noise issues I'm getting. Acts as a clean boost as well.
IMO—it's over-priced (@ $240). I recommend considering FullTone's Supa-Trem (@ $150) before committing to this.
