EXCELLENT Product for using with the dash mount BUT not so good for all cars with the vent mount.
This is a great product for wireless phones worked perfectly for my SG S21 the mount is really good sturdy flexible and firm if done right. BUT the vent jack plug is short for my Camry 2018 doesn't hold the phone firmly. It keeps wobbling when driving. So if you're looking for using just the vent holder make sure your car has a short AC flap so it can mount the plug firmly hold the phone properly. The phone holder is amazing it works really good just the way it is shown in the description. So guys first check the flap size of your cars AC vent must be short if you're looking to use the Vent plug holder. But if you're going to use it only with the dash mount its fantastic and holds the phone really firm and good. I really love this product and highly recommend to buy.
