Review on Greenlee 608 5 Piston Conduit Types by Todd Payne

As a result of my tests, I determined that these pistons were a huge disappointment. While they may be helpful in certain situations, they were NOT up to par with other options on the market. The only positive thing I can say is that they are made for industrial and scientific use .However, the cons far outweigh the pros. They were difficult to use and often led to incorrect readings. Overall I would not recommend this product..
