Got my dock and guides the other day. Works great with my iPhone X with rather thick Spigen Neo-Hybrid case. I was surprised that it didn't come with the screws for installation, but luckily I already had the Tesla dock connector so I used the screws from that. Mine came with a straight cable (i.e. not right-angle) and it's long enough to reach my high speed charger in the cigarette adapter. The phone is nice and secure and I'm sure it would hold up to Ludicrous acceleration (maybe even "Plaid").
Excellent point about the screws. This is exactly the type of information and feedback we looks for. We can certainly try to include it in our future items! If you have any more questions we're here to help! Stay tuned for more products soon!
