Working great!
I've used this for three months in a power monitoring application on an off grid house. It monitors Line 2 of the 240. and I have a much more expensive LEM on line 1. It works exactly like the fancier version for much le$$. I would buy it again.

Bought 8, 1 DOA
I’ve used several of these for sensing power on Woodshop tools and automating dust collection. 7 have worked great, but 1 doesn’t work at all. Unfortunately I ordered multiple at once in early October and it took some time to set them up, so by the time I discovered the dead one the return window was closed.
