Professional reviewers consider the Powerextra DF-400 a solid entry-level flash that offers good value for its price, thanks to its GN 33, full head swivel, and wireless slave capabilities. However, they note significant drawbacks such as the lack of TTL/HSS, a relatively slow full-power recycle, and a plastic build that feels less robust than competing models.
Everyday users praise the flash for its low price, long battery life, and ease of use across many camera brands, while repeatedly criticizing the cheap plastic construction, slow full-power recycle, and inconsistent performance at very high shutter speeds.
Professional reviewers praise the FK300 for its intuitive control layout, especially the plus/minus buttons, and the innovative continuous blue light mode that aids focusing without firing full power. They note the flash's simplicity and the broad flash duration range as strengths for creative lighting, while acknowledging that it lacks advanced TTL features found in higher-end speedlites.
Everyday users highlight the solid build, easy usability, and the value of the included accessories such as the magnetic filter and stand. The adjustable power levels receive consistent commendation, and the price point is seen as a strong advantage.
