Good little meter
Great everyday meter from general maintenance, can perform basic diagnostics (continuity, resistance, voltage ac/dc, maybe a couple others, off hand can’t remember). If you routinely need more advanced diagnostics, not the meter for you. Otherwise tucks away nice in your bags and about half the weight and size of a full on meter.

Works fine but connection loosen easily
This is an accurate and functional multimeter. The display is clear, it's easy to hold and it has plenty of uses. The one issue I have with it - thus the 4 star rating - is that the connecting plugs on it tend to slip out as your using it which makes for a frustrating experience at times. They seem to be pretty standard connectors but they don't have enough grip on them. Otherwise it's good unit.
