Mastech is generally a good brand.
I trust Amazon
reviews **not at all** anymore.
Google with exact model# and see derailed tech
reviews with discussions in the specialist
forums.
Note the ability to measure surge / startup peaks - often **very** short duration - is something only the Fluke-level $209-400 units can (try to) do.
Real geeks apparently use very expensive ? oscilliscopes ? for that.
