Recycle time

About 6-7 sec at 1/1, and almost instantaneous at lower levels in actual use.  Recycle times are longer when pushing the test button at all except 1/1.

Power saving function

Yes, after three minutes it goes into sleep mode, but will never turn off completely; wakes up after pressing any button on flash, or the camera's shutter button, but wait for red charge light before using.

Five full levels only; 1/1, 1/2, 1/4, 1/8, and 1/16.

Wide angle diffuser type

Plastic clip on, covers down to 20mm, (14mm APS-C) and shows on LCD when attached.

10.4oz (295g) without batteries, 14.3oz (406g) with batteries.

Operating temp

Not listed.


LCD review and menu functions are sometimes cut short or cancelled when flash is mounted and turned on, must be the flash is powering discreet actions, similar to half pressing the shutter button and returning to the default screen.


Has adjustable power levels and zoom features which are rarely seen in this price range. 

Good for

Great for off-camera radio controlled flash use in manual mode (Radiopoppers tested), plus it won't shut off in the middle of a photo shoot after a short period of inactivity.  Could be a very economical choice for on-camera occasional flash use, just remember to adjust the zoom position.

Not good for

Fully automated operation, wireless optical use, or people wanting HSS.


No, quality control is awful, do not buy!
