All the other ways you tried hanging your pictures and wall mirrors just so failed. Having said that, you had been using typical measuring and leveling tools that were really only designed for one purpose. They also turned out to be pretty awkward to use, particularly when trying to position yourself carefully on a small step ladder. It turned out to be a precarious operation, a recipe for disaster.
And in the end, you could never, ever reach those hard to reach places. Now though, there is a very easy way to hang pictures. This is made possible through just one precise tool. It is an easy to use device that combines a number of tools all into one. This is a tool you need to use if you have always struggled to take measurements with a tape measure or trying to reach a center point. This easy to use device is a multipurpose one. It allows for precise measuring, leveling and placement. It has an auto centering feature installed. This feature makes it quick and easy to find the center of a space or object.
The device also has a locking screw. This screw allows you to precisely transfer a dimension from a template or project to where it needs to be placed. Bubble vials have been installed to allow you to seamlessly level all projects while you align and mark them up. The device is not a heavy weight implement in the physical sense. But it certainly is when you consider what it can do for all your DIY projects and in comparison to all the other devices you have been using up to this point.
So, hang all the other tools, and hang your pictures up right this time.
