GREAT FLASH FOR THE MONEY
I LIKE THE DISPLAY ILLUSTRATING ALL THE DIFFERENT OPTIONS AVAILABLE AND FRIENDLY TO USE.
EnriqueTSep 11, 2026
Good for individual
I bought this to use with a remote flash set up with my older model Nikon. I worked on camera but not off camera with remote.

Great Easy to use Flash!
I bought this to go along with my new Canon EOS Rebel T7. Works easily and perfectly for me. I use it primarily for close up miniature photography. Much better to work with than a Ring Flash in my experience. Using the EV adjustment is quick and easy to make some great photos.

Highly Recommend
This flash works perfectly with my son’s new Nikon that he got this past Christmas! He can use it on and off the camera.

Nice camera attachment
I purchased this flash to brighten my pictures for night time scenes. It definitely added more light and it provides you with several options to adjust the flash brightness and speed.

A Good Flash for Tight Budgets
This is a pretty decent flash. It’s versatile. I like that I can adjust the brightness of the flash.

Decent
Decent but not the best would recommend paying extra for better quality

Don’t buy
This flash is trash. I used it once they gave it away to a beginner. So I guess it isn’t trash but bad quality for an experienced photographer.
