1Zero Magnetic Phone Car Mount 14-Inch Gooseneck Long Arm Extension, Universal Windshield Dashboard Industrial-Strength Suction Cup Car Phone Holder with 6 Strong Magnets, for All Cell Phones iPhone

These work amazingly well
I’ve tried the sicker magnets but in the Florida heat they fall off and seam to lose their strength. I purchased this product and let me tell you it’s a game changer. They are super strong. I love thar you can move and adjust it as needed. I plan on buying more for holiday gifts later. They are well worth the extra couple dollars but hoping the price comes down a little as we get closer to the holiday season

HOLY COW! This sucker REALLY sucks!!!
This device hangs on, and doesn’t let go! I mean, neither end wants to let go. It reminds me of a deep sea creature from a 1950s horror movie.The suction head that attaches to my inner windshield is very easy to use. However, once it’s attached, it does not want to let go. I honestly find myself being ever so gentle when removing it. There is a genuine fear that I might pull my windshield out, the suction is that strong. (Logically, I know that’s not possible. Nevertheless, I am VERY careful when I remove it to clean my inner windshield.)And, it’s exactly the same for the magnetic head to which you attach your phone. I glued the magnet to the back of the cell phone case that it came with.After about 2 weeks of regular use, I removed my phone from the phone holder, and the magnet remained behind.I really wasn’t surprised by that, in fact, I may have actually expected it. It was a wrestling match between me and the magnetic cell phone holder when I arrived back home each evening.My solution was to slip a fresh magnet pad between my phone and my cell phone case. This worked as I had hoped — the attraction between both magnets was now reduced to the point where my phone was still functionally and safely held in place, yet much easier to remove at the end of the day. (I understand that iPhone users have to be much more careful about where they place their phone magnets.)I should mention that I’m a rideshare driver. I drive all kinds of roads, and mostly in city neighborhoods. For whatever reason, the nearby roads and freeways are in very poor condition and my car has to deal with hundreds of dips and bumps per hour. Those road shocks are immediately transferred to the interior of the car, and to my magnetic cell phone holder.There is a length of flexible, rubber covered aluminum between the magnetized phone holder and the windshield suction cup. The shock is not transmitted to my phone. However, the phone does bounce up and down because the aluminum works exactly like a spring.My car has a touch screen, and I’ve learned it would be very expensive to replace. In the first day or two that I used this, I noticed that my phone could have smacked into the glass panel and caused me over $1,000 in repairs.Not a problem, because this cell phone holder removes (fairly) easily, as I mentioned above. All it took was a minor repositioning to make sure that my bouncing phone didn’t impact on anything expensive on my dashboard.I’m not sure that this device would be useful in a wartime situation, but it does feel like it was designed for, and built to be used in a combat zone.I can’t think of any other products I’ve used that have been so simple in their construction, that have so completely fulfilled their promise, and that I have felt so positively passionate about. (With the possible exception of chocolate chip cookies…)I’ll close with this — this is the fourth cell phone holder that I have purchased recently. The first three were the sort that clip onto your dashboard air vents. They either broke, or failed in their duty. That experience taught me that I can’t use the clamp-type holder since I need to frequently look at my phone up close. The obvious solution was to go to a magnetic phone holder.I’m so thankful that my fourth attempt at finding a functioning phone holder was so successful.

Great as a XM antenna holder.
I bought this to attach to the outside window of my Camper as an XM antenna. Works great!! I put the phone magnet on the bottom of my XM antenna and then attached it to the holder. Attached the holder to the window outside via the suction cup. It Works great! It’s stood up in the heat and cold, and rain and snow. When I am done with it I just un-suction it and put it in my trailer. Makes is to easy. The arm is easy to bend to the direction or height that I want. It’s been a blessing. No more antenna falling off the room etc.,I would assume it would be great for a Cell phone but did not use it for that.It works!!

I used for my tablet in the tow truck which is working for couple months properly

This is all you need if you like to keep your phone in place while driving, magnet is crazy strong, wont budge!
