00:00 - Introduction
04:24 - Tweezer design
06:28 - In use
08:58 - Downsides compared to the SmartTweezers
11:53 - Dodgy Readings!
13:14 - Automatic mode 2nd parameter measurement
14:48 - Scope Measurements
17:38 - LED measurements
18:53 - More measurements
20:00 - Calibration Mode
21:24 - Voltage Measurement
23:13 - Charging
25:43 - The problem with the charge lead
27:46 - Conclusion
TLDR; It's not very accurate, doesn't have much resolution, limited ranges, accuracy issues between Auto and Manual modes, can't be used while charging, lose the custom charge lead and you are screwed, tilt head detection has a bit of an alignment issue, LED testing is limited, and the secondary measurements basically don't work.
But for $70 it's very handy and nothing else can touch it, and the probe design is gorgeous.
Absolutely no match for the much more expensive SmartTweezers.
Maybe they can fix some stuff in firmware to improve it.
