Absolutely a necessity if you plan on doing a large scale concrete job. My husband is tackling out 500 foot driveway; he may never use them again, but they were worth the money for the ease of use in completing his task.
Muy buen producto la verdad estoy satisfecho con mi pedido pues podr_ ense?arles c_o las uso pero no e tenido tiempo de grabar o tomar una foto pero en cuanto obtenga eso subir la imagen muchas gracias
So many jobs over the years on a bit of board and knee pads, laying out planks etc.These are not cheap but a must have even if you only use them once or twice a year.
