This is a goon, effective machine. The only comment I mite make is to read instructions. The only variance I would note is when using premixed dry products such as Sackrete or Quickrete, do NOT load the dry products first and water second. This results in large clumps of dry product sticking to the drum, even if machine is running when fluid is added. Put the liquid in first and immediately turn machine on to ensure complete mixing.The instructions say to a. Gravel, sand, cement and water in that order, then turn the machine on. This keeps dry cement from hitting the drum and forming dry clumps.
