This 220 LBS VEVOR Refrigerant Scale is super easy to use. It comes with nice sturdy plastic carrying case. The scale itself feels and looks robust with a rubber piece on top to keep the top from getting damaged as well as keeping your item from sliding around. The controller is easy to use and best of all it is battery powered and portable. There is a specific location in the case to keep the battery so it doesn't corrode and damage the inside of the controller. My only wish is that the cord was a little bit longer. I am fairly tall so standing up straight and holding the controller lifts the scale off the ground as the coiled wire does not stretch enough to leave the scale laying flat on the ground.
