Review on 📸 Altura Photo AP-305C Canon Flash with Manual Trigger - Camera Flash for Canon R, RP, 90D, 80D, 70D, SL2, T7I, T6, T6I, 5D, 6D, 7D, M6, M50 - 2.4GHz TTL Speedlite for DSLR and Mirrorless Cameras by Javarie Malick

This is a good value product for people like me who are not familiar with these things. The manual is poorly written, which DG must be aware of because they have provided a series of videos to try and explain its use. However, they are full of explanation holes and are more like product advertisements. Eventually I got a trigger that affected the flashing of the speedometer but was never able to control the power settings (in manual mode) as shown briefly in the various videos. Then it stopped working at all. After an hour of resetting everything and resetting my sync settings, I'm pretty sure I've exhausted the setup error issue. I would return it but I waited too long before discovering all this.
