The ARMOR-X Mini Flexible Phone Tripod is a smartphone tripod that is designed with flexible legs to rest on virtually any type of surface. Other tripods have proved useless unless I conveniently have a flat surface in front of me, which is why this particular tripod was appealing enough to try out. The ARMOR-X is compact and easy […]
You don’t need to get an advanced degree and take out massive loans to become a coder. This bundle of 10 courses was designed to teach anyone to code at home for less than it costs to go out for dinner. I was particularly impressed with this new 2017 bundle because it includes courses on […]
