## Customer Reviews

### ⭐ Horrific! Extremely Inaccurate!
*by K***R on May 30, 2025*

Horrific! Voltage reading off by at least 22%. Current measurement is not even in the same universe. Current displayed 6.3 Amps on a verified 1.4 Amp load. Do not waste your time and money on this meter!

### ⭐⭐⭐⭐⭐ works and you can read it without getting whiplash
*by 1***F on November 18, 2022*

Seems to work good, probably just like any digital sampling of current maybe 10% deviation from other inline meters in my installation. Very readable display with different summaries available at the push of a button. Sooooo many bad reviews of the blue one get this black on taupe liquid crystal one.

### ⭐⭐⭐⭐ Incorrect auxiliary battery polarity in data sheet
*by F***N on November 8, 2022*

The included data sheet (11/2022) mentions connecting an auxiliary battery to the 3-pin connector when the battery source being monitored is less than 4.8 volts. This is because the device itself normally uses the battery being monitored as its own power source. But the device needs at least 4.8 volts to operate. However, the diagrams only show a 2 wire connection without indicating which of the 2 pins on the 3 pin connector to use. It also shows to connect positive auxiliary battery to the top most pin. However, the video in the product descriptions clearly shows the black (negative) wire connecting to the upper most pin and the red (positive) auxiliary battery wire connecting below it which is the middle pin of the 3. I tested applying an auxiliary battery with positive to the middle pin and negative to the top most pin and it worked.The similar device ASIN B0B8VWNY9X has photos with labeled PIN numbers and functions that agree with the above.The resistor that senses the current is inline with the negative return ground lead not inline with the outgoing positive lead. The positive input lead is hardwired directly to the output lead on the circuit board. Not a problem unless your load gets its ground connection somewhere other than directly back to this device’s ground lead. For example, in an auto application if the load is grounded to the vehicle chassis.Circuit board is well made and clean.
