Pros and cons

Pros

USB and XLR options accommodate a simple computer setup or a separate audio-interface or mixer setup.
USB mute and gain controls plus a headphone jack support convenient adjustments and monitoring while recording.
A shock mount and detachable windscreen are described as included, with the shock mount intended to reduce vibration and the windscreen to help with plosives.

Cons

The arm stand and XLR cable are not included, so an XLR setup needs separately supplied equipment and mounting may require a compatible stand or arm.
