Would give it 3.5 stars if I could. It does the job well as a solid temporary mount for the car, but there are a couple of things I’d change.
I’m not a huge fan of the exposed underside or the supplied nuts and locking washers — I reckon Nyloc nuts would have been a better option.
The frame fits the Starlink Mini really well from underneath. The top section fits securely too, although there’s still a small visible gap once everything is tightened down.
The magnets feel very strong and I’d have no concerns using it on a steel roof. I’m planning to mount mine on the tonneau cover of my ute, so I’ll need to add a couple of steel strips first for the magnets to grab onto.
Overall, a solid and practical mount that does what it’s meant to do, with just a few small details that could be improved.
