Not bashing, but I switched to jb4 after 2 weeks of issues with procede and have been running for 2 months or so now with no ses lights, hesitations or problems whatsoever. Plus the few times I've emailed Terry with basic questions I had answers within 15 minutes tops. Impressive product and outstanding support.
