Review on Nite Ize Original Steelie Magnetic Mount - The Ultimate Solution for Metal Surface and Phone/Tablet Attachment by Nick Griffith

Excellent base. This magnet on the bottom is very strong and easily holds my iPhone 7 (the jack on the phone is another story) but that's another review. It also has a soft silicone ring on the bottom to prevent the mount from scratching the surface it's attached to. I like this base mount more than the regular steel mount because it can be taken from car to truck, tool box, golf cart or anywhere. The base magnet is strong enough to hold your phone upright without slipping.
