4Good Quality
By Jon Anderson
Sturdy and well made. The spring for closing the jaw opening is a little too weak in my opinion, but it still works fine.

5I wish I could give it 4 1/2 stars
By Randall R. Anderson
Quickly this is an easy to use and I believe accurate tong meter. It's small size allow it to fit easily in a tool pouch. It does everything I want. I have cracked the display in my pouch. I'm now a little more careful how I put it in my pouch. I wish it came with a hard case. I'd probably still keep it in my pouch. My only issue is that it doesn't have an auto off and I'm forever putting it away with the power on, wearing out the battery. I also bought the 110 volt plug adapter that allows me to read one leg of the power cord of an appliance without spearating conductors. That's been real handy.

4mini DC clamp meter
By Anthony Perry
Low DC current range makes this meter ideal for trouble-shooting auto electrical problems. I used it to pinpoint a relay problem on my air-conditioning circuit without disconnecting the wires or connectors.

5Usefull AC/DC Clamp-On Meter
By Stephen D. White
This was recommended to me by one of my customers, so when I needed a DC current clamp-on for a task with another customer, I purchased one. It does the job quite nicely.

Resistance levels were spot on, at every level. Worked great for my application! A bit pricey, but oh well ....

4Cheap alternative to most
By Foto Fun
Works really well for occasional use. I wouldn't use for commercial applications, as the switches might not hold up in constant use.
