I was hoping this would work well, but I’m not really impressed with it. The magnet is strong and definitely holds the phone well. It also charges the phone very well. It is also fairly easy to install. That’s about the end of the pluses. Using the rubber devices they give you to help run the charging cable is something to be desired. They have not done a good job of sticking. Either it comes completely off from the car, sticky part and all, or the sticky par stays attached to the car and the rubber cable holder comes off without the sticky or Velcro part. When it’s holding the phone, if there is any kind of vibration, it shakes the phone even more. It doesn’t seem to want to stay tight against the screen. I keep having to re-tighten it so it won’t fall off. I’m already looking for another phone holder.

Looks good, fits good, works good

Style: Charging MagSafe Mount

I LOVE it! I bought the one with the cord at first and then returned it for the one without the cord and I'm 100% in love with it. It looks good, the magnetic strength is awesome and I love the fact that it can swivel around too

Very slow, but good quality

It works as expected, but my phone says that it is a slow charger even when plugged in my fast charger brick. False advertising. Really wish it charged a little faster
