I'm not a woodworker or a carpenter, but I'm not a fool either. Everything arrived as advertised and I used some of the parts in fitting a new door today. The beats were very accurate and appear to be well done. I saw a review where someone complained about the box…. really a man? In any case, today I am very satisfied with the price and the quality of the work. However, I will be using them INTENSIVELY for work over the next few weeks; Durability must therefore be tested!
