Multimeter
Easy to use. You do not have to figure all the different settings
Lance Mungo –
Good product and especially good price, for an autoranging meter.
Comes with a decent carrying case. The probe connectors have plastic covers which have to be removed before they can be inserted into the meter. The instructions do not mention this. The covers are tightly fitted; fingernails and hard pulling will remove them. Comes with batteries installed which you will have to remove if using the meter infrequently.

Great Value
As soon as it showed up I put it to work biasing a tube amp. Worked perfectly…immediately went auto to mv, no turning a dial like my old multi-meter. Great product!

Just a DIY guy –
Awesome meter with great value!
I wish I would’ve bought this little unit a lot sooner! It detects voltage without contact, has a nice bright screen, and seems like it’s going to last for years to come. It is compact enough with the small carrying case to fit into any tool bag, I like that it’s not weighed down and bulky like my older HF unit. This unit functions as well as others costing significantly more money
Boots –
I should have replaced my old meter sooner!
I like this meter. It is “intelligent” , meaning you don’t have to set a switch to detect AC or DC

A good handy multimeter which will be used to check fuses and batteries around the house. Also, the NCV function is good to check for live wires and broken points. What I wished this meter had was a button to select between the voltage and the resistance function, but I found that the response is almost instant.
