A Nissan will do the same thing as a Lexus for half the price, too.

When it comes to electrical tools, I'm trusting my life with its only ever klien or fluke.

Imagine flatlining in an ambulance, and the paramedics go "check out this defib I got from wish, it'll do the same thing for half the price"

It is a very good meter, I use Fluke but most of my co workers use that same Klein meter. Great price for sure.

This is a pretty good deal for a clamp meter that can do DC current. I paid $10 more in March. That said, I don't use mine enough to say how good it is.

Is this good for low voltage use cases and reading current (RC, electronics, etc.)?

Our community has rated this post as helpful. If you agree, why not thank clsA

I got this a few weeks ago for use with my solar panels and 100ah batteries in a solar shed.
The DC Amp clamp feature is the main reason I went with this one over others. The screen is also great on this version.

I highly recommend getting the magnet clip to go with it Klein Tools Magnetic Hanger 69417 - The Home Depot [homedepot.com].

Thank you. Solar was my purpose as well. Was getting ready to ask, but... so thanks.

I have this exact model with the dark screen. It's a pain in the ass if you're using it outdoors. I wouldn't buy it again although it's not bad enough for me to buy a different model.
