The magnet is very strong and holds my lPhone SE in place except on bumpy roads

It holds my phone (Samsung Galaxy 5S) in portrait or landscape mode and is not effected by bumpy roads.

I had mine sticking straight out of the dash for a while and eventually it fell off (heat + bumpy roads)

The only problem I have is when the road gets bumpy, my phone shifts

Magnet is strong enough to hold phone over bumpy roads, just not in

With phone in the vertical orientation, rough/bumpy roads can cause the phone to bounce downward; one solution is orient the phone horizontally - then vibrations don't have much of an effect.

Hasn't dropped the phone on some really rough roads.

I drove the car on bumpy roads, the phone did not fall or shifted

Holds phone firmly and phone does not drop even if you're hiding extremely bumpy road

It holds my cellphone even on bumpy roads

Yes, the Steelie held my phone securely through several abrupt stops, sharp turns, bumpy roads, going 70-80 mph most of the way

magnet not strong enough to hold phone wile one rough roads

tilts forward especially when you're driving a bumpy road

The phone tilted further down every few seconds while driving along smooth roads, and abruptly tilted down when I hit a bump

On smoother roads and asphalt the Steelie worked just fine

Mine is going in my 4runner, so time will tell if it holds up to bumpy roads without sagging.

It doesn't fall off the ball, but within a minute or less of driving on a regular smooth road, the phone droops down and angles away from where I had it until the bottom of the phone touches the dash and it can't droop any lower

I was a little worried that my phone would come loose and drop to the floor when driving through rough terrain or bad roads

only draw back is my I phone is a little to heavy and will tilt a little, but has never come off even on rough road

Works great even in very bumpy roads

I commute over 100 miles/day, over some pretty torn up roads, and my phone (Samsung Galaxy S6) does not shift at all

With the large magnet my phone will stay exactly where I put it no matter how I drive, how bumpy the road is or if I'm charging it vertically or horizontally

yeah, it stay attached to the magnet the whole time, but when the car is moving fast (like in the freeway) or rough road, the phone always move to

I drive a F-450 truck that is EXTREMELY bumpy and I drive on some of the poorest maintained roads in the northeast

On really bad roads or at slightly higher speeds on less-bumpy roads my iPhone 6S would bounce off

My only complaint is that due to my heavy phone (iPhone 7Plus), sometimes it will angle downwards when driving on a bumpy road

It holds the phone very well, even on very rough roads . . . very good quality.

Unfortunately, my experience has been that any amount of rough road will cause it to fall into undesirable positions

Unless you are driving on a absolutely smooth road (hard to find those) the phone will be facing the floor board every time you hit a bump

Such a simple idea yet works great even on sime of the nations roughest roads.

It droops slowly on a smooth road and immediately on a bumpy road.3.

I drive a pickup over rough roads in the oil fields of west Texas

Even stays when traveling rough roads such as OKC and off road when delivering or picking up

The only thing I would add is a little rubber pad on the part that touches the back of the phone but it still works as it should with the way it is

We’ve tested both and mine doesn’t magnetize the things nearly as well as his

and now that I’m missing a

Once I did this everything works as
