Good quality
Great product. Like that you can clip it onto the insulation of the wire, instead of being on bare metal. Safer for use. Good price. Simple to use. Would buy again.

Safe, reliable, and easy to use!!!
This unit is great for safety as all leads are very well built. Clamps are covered and the risk of exposure is very limited due to the design of the product. Well thought out product that is very easy to use. Also comes with great instructions to clarify any questions you may have. Works consistently in hot and cold environments and never gave us a problem to date and that is hard to say about a lot of products now a days. Solid A grade!!!

Does not work on 480v Delta
The media could not be loaded. Works as expected on 480 volt wye. Results are inconclusive on 480 volt Delta. I like that it has 4 magnets on the back. Comes with a soft side zipper case.

so easy to use
Absolutely Fandamntastic! I love not having to worry about alligator clips failing or making accidental contact to something they shouldn’t in live gear. Absolute Game changer with this, much safer and easier to use.

Works as good as our Fluke Fluke 9040!
I was recently testing a custom 30kVA 480V Delta Primary 208V Secondary. My company has a Fluke 9040 I started verifying the phase rotation with the FLUKE meter, but after discovering our building was wired by utility with negative rotation (counter-clockwise) and my transformer had some core windings swapped, I decided to invest in a phase meter for myself. The Extech 480500 meter's specs are very good and owned by FLIR who I have a lot of respect for. The meter worked just like the FLUKE 9040 and cost less than a third of the FLUKE meter. Very satisfied!!

Must have for electricians.
Stop clowning around with the alligator clips on the average rotation meter,Trying to clamp on to some live component.This unit works fantastic!Clip it to wires anywhere convenient.

Looks cheap but works GREAT
If you’re looking for a meter to test rotation for an electric 3 phase motor. This is your product. Had the best price I could find for the frequency of use. Doesn’t require batteries so you save money there. Mine was packaged well, nor was it damaged. Fast delivery and worked like a charm at its max rating
