I am a some what advanced do-it-your-self-er, bought this Speedy Screed two months ago, have used it on four cement pours totaling forty three yards of cement and this tool is a work saver. It is a very sturdily built machine which easily attaches to your screed board. I just use two by fours. I do attach a one foot, one by four, perpendicular to the screed board at each end to help stabilize the Speedy Screed in a upright position while using it. I did have the coupler, the part that connects the motor to the drive unit, break and called Bon tools concerning the coupler. They were very nice and immediately sent a replacement coupler at no charge. It was an easy fix. I've got to admit, I was rather pleased with the attention the people at Bon gave me in getting the Speedy Screed up and running, a big plus! That is one of the reasons I'm giving it five stars.Keith
