The trigger does not work, tried both the triggers. It touches the screen but not enough to click on it. Also the screw dint have the cushion as shown in the description. It gave a scratch mark on my iPhone 8 Plus back. I had another clip type of triggers one with red buttons they worked very smooth. It’s clip broke but still tried to test, used while holding it with one hand and still it worked so it’s not mobile issue. Have initiated the return, will try some different model.
