Real Customers, Real Stories
👍 “Perfect fit and keeps the phone stable and out of the way. Charges fast.” – Stefano Miraglia
👍 “The little “kickstand” in addition to the clip on the AC vent really helps stabilize it. I love that. It’s a couple inches off the vents so the air can still circulate. The magnet has been very secure for me as well and I live on a bumpy dirt road. So far, great product. FYI, i drive a Fiat.” – Roxanne Darling
