This machine was a little difficult to assemble exactly according to directions, but we were able to get it together and working well in a couple of hours. There seems to be a slight leak in back because we haven't been able to properly level our unit. Still, it works very well, runs quietly, arrived quickly (without any big dents!), and was less expensive than simpler models sold in local stores. We are very pleased.
