Superb clamp multimeter at an unbeatable price and remarkable precision for its cost! In terms of convenience, I appreciate the long press on the power button, which is missing on the internal resistance tester. However, I would have preferred front-facing connectors and a rear stand clip to keep the multimeter upright like others. I will update later with more pictures.

FNIRSI® LCR-P1 LCR Transistor Capacitor Tester

With the new DPOS350P tablet scope Fnirsi have taken a leap forward in performance and quality. As far as I am able to test (I don't have a 350MHz signal generator) the device meets the published specifications. The build quality is excellent - metal and high quality plastics - the unit is reassuringly solid in the hand. The touch screen is very bright and responsive.I like the Bode plot feature - although I wish it could go down to 20Hz to cover the whole audio band, and some averaging would probably tidy up the phase measurement. Maybe this can be addressed by firmware updates?It won't replace my Rigol 900 series scope, but the very fast boot time of the Fnirsi (a few seconds cmopared to ~1 minute for the Rigol) will make it the go-to scope for quick measurements.I do hope that Fnirsi maintain this level in future releases.

FNIRSI® DPOS350P 4-IN-1 Digital Tablet Oscilloscope Signal Generator Spectrum Analyzer Frequency Response Analyzer

Excellent clamp for the price—precise, responsive, and very capable when measuring internal resistance. The clamp is surprisingly versatile: it supports even the tiny 10180 format, and with a bit of pressure, it also accommodates the larger 21700 batteries thanks to a clever spring-loaded lower contact. The included tester probe is also outstanding, featuring comfortable spring-loaded tips that make handling smooth and reliable. A great tool overall, especially impressive when compared to more expensive professional devices!
