Even with the weigh of the phone, everything stays in place very nicely, even over the bumpy roads where I live

After many hours of driving, sometimes on rough roads, the phone has remained firmly in place.

The magnet is strong and does hold up well, but if you are on a bumpy road, expect it to bounce off

Works exactly as advertised and holds my Galaxy S8 securely even on bumpy Los Angeles roads

The magnet appears to be strong enough to hold my smartphone even on bumpy roads, but this is new to

Slipped the magnet under my case and even on bumpy roads works super well with me iPhone 6s - this is a lot easier to handle then most other holders especially for the price

It's good, but you'd better be driving on a smooth road

Like it, holds my phone (LG G2) well even on rough roads, convenient, easy to install and move from one car to another, but inexpensive enough to buy one for each car, but... one significant drawback: if your whole vent rotates up and down like my Tundra then the weight of the phone pulls the vent to the bottom of its travel.

Holds my Note up even on bumpy roads as long as your sure you got it squarely on the magnet otherwise it will fall off

I was concerned at first that it might fall off on bumpy roads, but I've never had my Galaxy S6 fall off the mount

Corners at speed and bumpy roads, nothing shakes it loose.

Easy to install, good magnet strength to hang on to the cell phone case, even when driving over bumpy roads.

Been over some bumpy roads and the phone stays put

Driving over potholes and bumpy roads has not made the phone fall from magnet

Holds even our I phone 6plus in place while the car is parked or at low speeds with no bumpy roads or sharp turns

Should probably work really well if you don't drive on bumpy roads and have a lighter phone.

On some bumpy roads the phone will move around some and actually came loose after a particularly nasty bump.

I think this application would be fine in the city or on the highway - as long as you can avoid any rough roads or potholes...or if you could hold the phone to keep it from slipping (I know- that totally defeats the purpose!

I've not found anything to hold my phone in place even on our bumpy roads

It does ok with rough roads and fast

Plus on bumpy roads it would jump around like no ones business

I drive an SUV and my initial concern was that the phone would just fall off going over rough roads and such but it hasn't yet

Holds her phone steady on even bumpy roads.

Coolest car mount on the market and surprisingly strong even over bumpy roads or fast corners doesn't slip.

Solid hold even on the toughest wash board gravel roads

My Samsung Galaxy S6 Edge Plus stays put even on bumpy roads

The problem came after I left the driveway: driving down the road - a somewhat bumpy, dirt road - the phone began to slip and the air vent shifted and gravity won

Holds the phone, doesn't interfere with the phone and sticks on the air vents and, so far, survived the bumpy roads

Magnet not quite strong enough, slips some on rough roads

The magnet is very strong, which is great as it needs to hold over bumpy roads and such, but it's so strong it pulls the whole device right off the vent

We live in West Virginia, and I have yet to have any of our phones come off of the magnet even on our bumpy roads

Works well holding the phone with our crappy roads but has scratched up the vent.-update 12/16

I have not had any instances of the phone falling when traveling over rough roads or speed bumps

It has a very strong magnet and it definitely doesn't fall off on bumpy roads.

All the other mounts would lose tension and the pho r would start to vibrate, I have not had that problem with this mount.

I have bought these for all of my phones, as well as my S/O's phones

I have had different types of phone holders, the suction cup...which sucks as it falls off always

I've had the mount now for probably 5 months and it is still as strong as when I first bought it

I've even tried driving slow as to not make it fall, but nothing helped.

Works as you'd expect.

It works exactly as it should, and the magnet works through my leather iPhone 6 case.

It'll work itself out a little as you put the phone on and off the magnet

The mount held an iPhone 6 in a Speck Candyshell Grip case as well as in a New Trent LV6 case while going over potholes, curbs and other bumps with minimal problems and with no problems if you are very particular about placing the phone's 'sweet spot' on the mount for maximum magnetic pull.

Strong enough to hold it in place, but no too strong as to make it difficult to remove

i did, however, deduct a star as the over all device did not work as

If you have a thick case it may not be able to hold your phone up because the magnetic element weakens as it is further apart

Works exactly as I expected it to

Works exactly as it's supposed to

You don't have to struggle as with regular car phone holders

Works pretty good on my 2011 Nissan Pathfinder with vertical vents, I have a Nexus 6 phone that is pretty big and heavy, it's vibrates and shakes just a
