Based on my experience this lubricating machinery automation is an absolute disappointment .It's marketed for "industrial and scientific" use, but it barely even works. One pro i can think of is that its easy to set up, but that doesn't make up for the fact that it doesn't do what it's supposed to. the cons, however, are numerous. The design is flimsy and cheap, and the performance is terrible. Save yourself the trouble and look for a different option in the power transmission products category..
