Review on CALOCAA Universal Compatible Smartphones Fluorescent by Sean Powers

This product is solidly built, has a nice weight and feels good. Very nicely finished in black with bare metal ball joints. It also has a nice rubber pad on the side of the magnet to cushion anything it's attached to. The arm is articulated with both bases (magnetic and adhesive) to offer a good range of angles. The ball joints are tight and hold their position very well. While it's certainly great for phones, I also recommend using it as a flat magnetic hinge base to attach other things to the sticky side such as magnifying glasses, mirrors, alligator clips, small flashlights, etc. so you can use the magnetic side to attach on metal objects. It would be great to work in tight spaces like the engine etc. I have one with a mirror attached to my manual espresso machine to see the bottom of its bottomless portafilter as I draw. Good product!
