I have been using this charger for several months now. I think the design is fantastic. I've seen other reviews which question the reliability of it. My experience has been the opposite. I have a folding phone so it's not light. The connection to the dash has remained intact without fail. I am careful when removing the phone. I don't just yank it off. It charges as it should. The magnetic force is what I expected. Holds my phone with no issues or concerns it could fail and drop the phone. It's super convenient to have this integrated design. My dash is already occupied with a portable android auto unit. My 4Runner is older and did not have that feature. Again, this is plastic. Handle it with some care and I don't see anyone having issues with breaking. It has worked out great for me. Recommend.

Great mount / Terrible charge rate

Love the mount. Easy to install and with a small piece of double sided tape under the top edge, it’s very secure… The magnetic mount is strong enough to hold an iPhone max (at least mine). The charging ability is where it falls short *BAD! It will charge but, barely.. If you’re using maps, making calls, etc.. the phone continues to drain at an alarming rate…

Not suitable if you have a silicone case.

I'm waiting for delivery of new phone case, as the silicone one I have on my phone will not hold onto the magnet provided for this holder. Installation was a snap and I love how it looks in my car. Cost seems fair for the product. Fingers crossed that it will work fine once I get a new case.

Charger portion stopped working twice now

Works well until it doesn't. Was excited to get the phone mount off the car vent but I have gone through one replacement already and now I'm past the point to completely return it. Twice now the charging portion has failed. The first one stopped lighting up completely with in about a week and now this one just constantly flashes and no longer charges after another few weeks. I have tried different cords and outlets in my car with no success. The magnet portion however is strong and does hold the phone well.
