Pros & Cons
Pros
Accurate and simple to use and good construction. Sometimes the w is more important than the land now warnings in the osd. Passed them around to all our rc group.
Been needing this for a long time. Works fine for whoop batteries, including hv. This is exactly as advertised.
White plugs make checking your pack voltages a cinch. Can check multiple battery types and connectors. I use the tester to evaluate what a my different chargers leave the battery at.
Between the tester and the adapters this is a must have for anyone using 1s lipo batteries. This is a must if you fly micros, whether its a quad or micro plane.

Highlights
Quality
Diminutive size makes it easy to bring along with the tiny quad
This thing is indispensable if you run a tiny whoop style micro quad with the bigger 2
Competitiveness
I only had a tester for my larger lipo batteries

But the pin spacing is off and causes stress on the pins that will lead to the checker pins breaking eventually
Posted by a reviewer on Amazon
Id rather spend a few bucks more to not scrap a checker and have to chance shorting a pack pulling broken pins

Doing this prevents the battery from going all the way to lvc low voltage cutoff and becoming electrically damaged over time
