Great
The VRP polish was not available so used the wipes, excellent results. I used it for my engine detailing, I also used it on my motorcycle for the plastic and restored the color.

Just OK
I did not care for this product. Maybe I didn't use it right but it was oily and left streaks on my doors and dash. The window cleaner was just ok.

Sturdy and secure
It took a few tries to get it positioned exactly as i wanted it but once that was done it hasn't moved. I have a Samsung s25fe phone with a case and it fits just fine. Seems secure. It does shake slightly while driving on bumpy roads but it doesn't move positions and I don't feel like my phone is going to fall. So far it's been great.

Quality cell phone mount.
The best cell phone mount I ever used. Quality is obvious after you easily install. This hasn’t moved since I placed it in my car. I like that it doesn’t block the air vent too. (You can move any angle you like). Won’t disappoint! Good buy!
