Review on 📸 AODELAN WTR2 Wireless Shutter Release Timer Remote Control: Compatible with Nikon Z6, Z7, Coolpix P1000 and More; MC-DC2, MC-36 Replacement Option by Jared Bradford

I bought this primarily for the bulb and intervalometer features to use with the Sony A7R4. Unfortunately, these two features typically don't work when using a wireless receiver to trigger the camera. This renders the device practically unusable. The manual and timer functions seem to work when the transmitter is connected directly to the camera (wired), but this is meant to be a wireless shutter release. When using wirelessly with a receiver attached to the camera, the problem seems to be the receiver randomly dropping/shooting the shutter line or not guiding the line hard enough. So in bulb exposure mode, pressing the shutter button will fire the shutter, but then the exposure will end (mostly) at a random time before I want it to. This still happens about 95% of the time when using WiFi. The same problem applies to using the long exposure intervalometer function - if it's long enough to require a manual exposure mode, then the exposure will most likely not be as long as you set in the timer.
