My hubby got this measuring tape for free from his company where he works. He works in a factory so his jobs are mostly involved with machines and tools. So this measuring tape is really a helpful tool that can help him in his workplace. The measuring tape is made by KDS, model YS-3005ME. It can measure at a maximum length of 3m or 10ft. There is a red-colored lock at the left side. So when you pull the tape out, you can lock it at the length you want by pressing the red lock button. It’s that easy! You can measure the length either in cm, or in inch. There is a clipper at the back of it, and this clipper is used to attach it to the belt or shirt pocket or wherever you want to clip. Its compact size makes it easy to carry or to clip. My hubby always carries it by clipping it to his belt when he goes to work. Some of his colleagues also got this measuring tape, and so far this measuring tape has done a great work for helping them.
