This is a game changer
I bought this a month ago. I use this on my side job work and I also use it at work. I just like how it helps make troubleshoot stuff.

    Great meter with lots of features for the price
    After reading the reviews from others and looking at the price for features this meter has I went with the Klein CL800 for my A/C and electrical jobs. So far it works great and the accuracy is fine for field work.

    Ok meter, hard to read screen and no tone with NCV
    Good feature set and feels good in the hand. I just hate how faded the screen gets at an angle or when I turn on the backlight. The last thing I want to do is have to stick my head in a box to view the screen or twist some wire. Also the NCV has no tone alarm, so strange. Normally I'm a big fan of Klein but I'm a pass on this tool. Fluke or Ideal clamp meters for me.

      quick & easy. [HD needs to increase review limit]
      voltage reading is my reason for getting this. a 2-3' extension makes perfect .. i added outlets & switches years ago & getting little shocks ,, but all is good finally with this tool . i suspect it was static carpet shocks. HD double write limit

        This is a great tester with which you can test and diagnose variety of problems such as improper wiring, faulty grounds, timing for tripping of GFCI receptables and most importantly - voltage fluctuations. This is particularly helpful when you need to diagnose and service generators, flickering lights due to deteriorating connections on your main panel and so on. For the price, it is a must have in every service van and toolbelt and a very good addition to a home's repair kit.

        Awesome tester
        This is the best gfci tester I’ve seen. You can check voltages on a gfci receptacle or a regular one. It also tells you how fast the gfci trips

          Good for voltage, amperage, etc., but not for temperature.
          Overall, the clamp meter is of good quality with acceptable results, when comparing it to the Klein MM700 multimeter. The discrepancy comes with using the thermocouple on the clamp meter. There was a sizable, erroneous difference when measuring ambient air temperature in a dwelling. My MM700 read 66.0F while the CL800 read 152.3. Upon switching my banana adapter and thermocouple from the MM700 to the CL800, the ambient temperature was only 0.7 degrees different than my multimeter. I contacted Klein Tools, informing them that I only wanted a new thermocouple and adapter. Unfortunately, they wanted the entire clamp meter with accessories back. Klein Tools, being a solid company, sent me a whole new CL800 clamp meter within 4 days. While there is some difference in temperature readings with the new CL800, I will use it more for voltage/amperage readings. As for the GFCI tester, I love it!

            This tester's model number is Klein RT250. It's a well design product with many features. Probably the most important features are: 1) once inserted, it shows the voltage of the power outlet; 2) for GFCI outlet, it shows you if there are any wiring faults; 3) it has a green light and red light, from where you can easily tell if there are any issues or everything is alright. There are two free batteries that comes with the package. The only thing I don't like is that the plastic package is hard to open.
