Matrix Magnetic Wireless Charger with Car Mount

I actually bought 2 of these, one for each car. They charge as expected, the magnetic ring works well, and my phone feels very secure on the charger. The car mount also works well and feels secure.
The only reason I have not given 5 stars is that when my phone is on the charger, I frequently notice the screen come on and the green circle appears, showing that it is charging and the amount of charge it has. The screen will then go off again, and then a couple of minutes later it does the same thing. This is not continuous, it can go for long periods of time without doing this. It looks as if it keeps disconnecting and immediately reconnecting. It's not a major problem, as it works, but I do find it a bit irritating, especially as it catches your eye when you're driving.

This is the third unit for different vehicles and they all work really well. Unit fits a variety of air vents and is very secure when vehicles are in motion. Thoroughly recommend these chargers.

Worked reasonably well, iPhone does not sit as securely as expected maybe magnet not strong enough

Great product
