MOTOBA 2 in 1 Car Phone Holder Cup Holder for Vent, Drink Cup Water Bottle Storage Air Vent Cup Mount Cradle

I actually screwed it down to a pull out cup holder I have on my 97 Ford F150, holds my 32 oz glass perfectly, and holds the phone very securely. Don't know if I would want to hook it up to a vent or not, might be a tad too much weight for some AC / heater vents. But it is a very nice product, and very reasonable.
