Do not like this tool at ALL
I will admit I am new to drip irrigation and installing it for the first time. The first time I tested the system, there were three places where I punched a hole for the 1/4" connectors, and it went clear through and punched through to the other side. What a pain to fix! Also this tool is dangerous. If it slips while you're using it, you may find yourself gripping the sharp edge of the cutting tool. I have done it, thank goodness I had gloves on. Poor design.
