  • Klein CL810 Review: The Meter I Trust on Every Job

    ByMike Izzo

    After fifteen years turning wrenches in attics and crawl spaces, I’ve learned that your meter either earns its spot in your bag or it doesn’t. The Klein CL810 earned mine within the first week. This isn’t another overhyped multimeter that chokes when you need it most-it’s the tool I grab first on every service call. What sets it apart isn’t just the auto-ranging or TRMS accuracy; it’s how Klein built this thing for guys like us who work in 130-degree attics and freezing rooftops. The LoZ mode has saved me from countless ghost voltage headaches, and the built-in flashlight actually throws enough light to matter. Yeah, it costs more than the box store specials, but I’m done buying meters twice. This one just works, every single time.

  • Klein RT210 Review: My Go-To Outlet Tester

    ByMike Izzo

    I’ve been carrying the Klein RT210 in my tool bag for the past two years, and it’s become one of those tools I reach for without thinking. As an HVAC tech, I’m constantly checking outlets before I install equipment, and this little tester has saved me from more headaches than I can count. It’s dead simple—plug it in, read the lights, done. No complicated menus or batteries to die mid-job. What I appreciate most is how it catches the wiring issues that’ll actually cause me problems: open grounds, reversed polarity, the usual suspects. The GFCI test button works every time, which sounds basic but you’d be surprised how many testers get flaky after a few months of real use. It’s tough, reliable, and priced right for something I’m not worried about breaking on a job site.
