Ram X phone holder questions

[Gone in 60]

Used the Ram X-Grip mount at my last job to hold a phone to the steering wheel of a racing shifter kart. The phone was the dash display. With no suspension you can't get much more of a torture test, and they held the phones just fine. Nowadays when I'm riding and need GPS directions, I put in a single Bluetooth earbud for voice directions and keep the phone in my pocket. I doubt I'd be able to see the phone in bright sunlight, and it shuts down if it overheats in the sun.
