Good meter for a good price.
I bought this to have in the house for small projects...testing batteries, checking receptacles, etc. Suprisingly, it seems to have all of the features of my Fieldpiece meter, at a fraction of the price. Plus the non-contact voltage tester is built in and seems to work well.

Compact and functional.
Works well enough for a homeowner to do minor electrical repairs. I purchased this simple to test capacitance on my ac compressors capacitor. My old meter did not have this as a function. Plus being 30 years old I needed something more up to date. Seem to be well built but don’t fool yourself. This is not a fluke meter or a Klein but for the price it functions as a good basic multimeter that will handle most homeowners needs. And will be accurate enough for most uses.

Good performance at a good price
A real value for such a capable meter. Did a Design of Experiments comparing it with a Fluke and found identical performance. Pricing was right, 6000 count, fit, finish, and especially the construction and durability seem good to slightly above average, but time will tell.
