Charges well and is sturdy and secure.
Color: PINK
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.

Charging phone holder
Color: PURPLE
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.

Well-designed but might not fit smaller phones
Color: BLACK
This is a very nice product. My only complaint is that it is not well-suited for my older Samsung S22 phone, because the phone sits so low I. The cradle that its power button is inaccessible. I solved that by fastening a small spacer onto the bottom edge of the cradle, and now it works very well. It would be a better product if the bottom edge of the cradle could be adjusted. Aside from that minor issue, it automatically grips the phone and holds it firmly, and there's a built-in battery so the ungripping process functions even after the ignition is turned off and power to the cradle is shut off.

Works Great
Color: BLACK
I really like the automatic closing feature when my iPhone is placed on the charger. I have a Pro Max and I thought the phone might be too heavy for the clasp and would move while driving. I have used both the suction cup and vent connector to hold charger and phone without it moving. The device also must have a capacitor or battery, as when the power is off to the holder, you can still press the release button and the charger opens to release the phone
