    • Real good quality
Excellent work better than I expected. I love the large strong body. Very accurate Best meter for the money.

    • Works great but very slow response time
For a unit that has all the functions this one has, it is a great buy! I would recommend it to anyone who has the patience to wait for the accurate response. It takes time for the meter to display the correct reading. If you are impatient you may not get the final (correct) display information. The display changes over time as it adjust for accuracy. It would be better if it did not display any value other than 'processing' while calculating the results. But it appears to be very accurate. The time delay does make continuity checking difficult. I would have only rated it 3 stars for that reason. However, given all its functionality, that set back is not as much of an issue! I'd say buy it and deal with the delay! For the price it is a no brainer! ... show more

    • Meter is useful and accurate
Accuracy seems good compared with other meters. Capacitance measurement feature is handy.

    • Get what you pay for or a little less
I left my beloved Simpson 260 in the office of a client over Thanksgiving weekend. The place was broken into and my 38 year old Simpson was part of their booty. That meter had survived 38 years of near constant travel--all 50 states, most of Europe and a good deal of Middle East and some of Asia. I am old school and OLD, so that meter was ideal. Go digital, everyone said. Fluke is great, but over priced they said. So I purchased perhaps the slowest multimeter in the universe. Yeah, it has lots of features for the $. About 1/3 the cost of a similar Fluke. It works, but it is sooooo sloooooow. I started doubting myself when testing it out. Why no reading? Oh, go get a snack or a drink and then you might see the digits. Of course that is a stretch, but this much is true, the time to read either voltage or resistance in real life WORK situations is indeed slow. I expected some slow compared to the analog Simpson. But, on a major check out, it grew tiresome waiting on the meter EVERY point. The more "bench" stuff, cap, and resistor testing is nice and a bit slow. To me, it was less of an issue in those modes. Side by side with an old GW//Instek bench DMM, the accuracy was right on the money. Backlight is a real issue. Have to turn it on....and have not found how to keep it on for any length of time. Big issue for some of what I need it for. Menu structure and keystrokes seem ok. Not the most intuitive, but then I am used to an analog meter. So I can accept some learning curve. Still on $75---not throw away, but not great value. For occasional use, it should be just fine. But there is, I have learned, a reason you see real Pros using Fluke. I try not to be swayed by a brand, but based on my early use of this unit, I can see why a pro would be disgusted with it in about 5 minutes. Again, you get what you pay for and if you are a limited user and have a tight budget it does offer a lot of features for the price. That reminded me that selecting tools is not just specs and $ to balance---you have to think about how you will use the equipment. Slow and no backlight (no always on for backlight) have colored my view of the unit. Perhaps that says more about my failure to research and test then it does about the meter or manufacturer. Not gonna send it back. It just might be the tuition I have had to pay to find what will serve me like my old Simpson did. ... show more

    • Best MultiMeter under $100 - Get it!
After thourough research to get the best bang for my buck, this was the winner hands down. It is a great balance between functionality and capability. I have found it has more than met all of my needs for it. I am only a hobbyist, but I feel safe with this meter, and it works great. I highly recommend it for anyone on a budget. ... show more

    • Didn't last as long as I expected
I liked this multimeter when it was new, but I didn't get that much use from it before it started giving bad measurements, even with a fresh battery. So, in the end, I was disappointed. And now I question my decision to buy.
