There's a Drift User's group on FB which reports a lot of problems with the Ghost XL.
Mine conked out in heavy rain last year but was replaced under warranty without difficulty. Without the warranty it would be bricked or bodged by my inexpert hand.
Recently, Drift sneaked out a firmware update (said to "improve live streaming") which had the effect of diminishing the video quality considerably, by reducing the bitrate and file size, and I had to spend weeks with their support people getting that replaced with the old firmware so my videos are back to an acceptable quality. The XL is meant to be fully weatherproof without a case, so no case is available, but the Ghost X needs a case. If I'm going out in heavy rain I either tape over the speaker vents, or use a different camera in a waterproof case.
I'd probably look at a Ghost X but buy it with a credit card or from the place which offers the longest warranty.
If you're happy swapping the batteries, then a used
GoPro from CEX comes with a 2 yr warranty and the later models have excellent image quality and the stabilisation which the cheaper Drift models lack. It depends if you're looking at producing beautiful footage, or just running the cameras for "insurance" or reporting bad drivers. Hope this helps!
