      Well built good quality product, just a bit of a faf to get the chalk around the line, once coated it works really well. It really is easy to use, the strength and durability is good and the cost is good.

      well built just like all the other Ox brand tools. Your not spending a lot but your getting a lot . I constantly drop this out of my pouch missing my pocket and it continues to work every time.I really appreciate the thin string makes a clean crisp line. great value for the money.

      Product does lay a thin line of chalk but know that with that you will need to reload chalk more frequently than you may be used to.
