i purchased this charger and was excited to install and use it, it worked ok for the first couple of days, and then kept disconnecting from my phone with red blinking led. i have the samsung case for my phone, even when removed, i still had the same issue. maybe better with a fold.
it broke the vent of my ford explorer on the first use. the vent mount i'd been using previously didn't damage it but this one did.
i managed to successfully install it on another vent (being extra careful to not break it), but the phone is very flimsy, because i can't tighten it... because the vent will break.
