Review: Works excellent but not comfortable leaving it energized and unattended - works great! Great product and seems to have good accuracy/sensitivity. I can clearly see the current change when adjusting airflow on a fan application and the numbers seems to correlate well with what the calculated loads should be. The only issue is I am scared to have it energized all the time. it was just too cheap to trust that it won't burn up if left on for days/weeks/months. I used it in an application where it is connected downstream of a contactor so it only operates when the load is turned on. if it had a UL listing I would have preferred to have it on the upstream side so I can monitor the in-rush.
Review: Good quality all around. Fear not. - Works as claimed and good quality display. 2 wire AC connections are simple with no regard to polarity. I epoxied wires at the connection for added stability.

### ⭐⭐⭐⭐⭐ Works excellent but not comfortable leaving it energized and unattended

I can clearly see the current change when adjusting airflow on a fan application and the numbers seems to correlate well with what the calculated loads should be. The only issue is I am scared to have it energized all the time. it was just too cheap to trust that it won't burn up if left on for days/weeks/months.

### ⭐⭐⭐⭐⭐ Good quality all around. Fear not.
*by T***. on November 9, 2025*

Works as claimed and good quality display. 2 wire AC connections are simple with no regard to polarity. I epoxied wires at the connection for added stability.

### ⭐⭐⭐⭐⭐ It can detect as little as 10 ma of current and up to 100 amps.
*by A***S on May 2, 2025*

It works great. I bought two of them. I had a mold problem underneath my house and I had to have my crawl-space encapsulated (sealed). I mounted them near my breaker-box to monitor my dehumidifier and my sump pump. Because GFI outlets are used and the sump pump has no electronics, I added an LED night light to the outlet connected to the sump pump. It draws 20 ma of current so that I would know if the GFI has been tripped or has failed. The current meter can detect as little as 10 ma of current. I have not verified its accuracy but it works well enough for my needs. The dehumidifier draws about 30 ma in standby mode.
