This has been working really well for me. I have it mounted on my dash and not the window and it is very sturdy. My phone charges well with this and it has never dropped my phone and doesnt wiggle with car movement do it is very sturdy compared to others iv had in the past. Easy to remove phone and put phone in without having to adjust size every time. Great for delivery drivers. I haven't used the vent mount and don't see the need for it.

My man loves this. He says it helps when he drives incase he needs a different route and his phone is needed. It is easy for him to use and fits his cellphone well. It seems to be very durable and keeps the phone stable and locked in place.
