DIVEVOLK SeaTouch 4 Max Underwater Smartphone Ocean Kit

The dome hovers in front of the lens, allowing water to get in between and distort images/videos. You have to get the dome placed absolutely perfectly for it to work, and as soon as you knock it (or god forbid want to take a photo without the dome), it takes another 15 minutes to reposition the thing. Water also kept getting into the dome.I don’t understand why the dome and filter can’t just screw onto the case instead of on a weird arm extension? If it screwed directly onto the case, in front of the phone camera lenses, literally all these issues would immediately disappear. Bad design, poorly thought out, a waste of $400 and my time.
