This tool makes a perfect compression every time. I'm using the Ideal OmniCon compression connectors only and haven't tried this tool on another manufacurerd connector. The manual recommends using Ideal OminCon connectors. I'm very happy with this pressure type tool and will not be using the "crimp style" connector on my cables.
worth the money. i like that the compression bit is preset and doesn't get loose or spin around, and the crimper design helps stabilize the fitting. worth the money.
