Pros & Cons
FNIRSI P02 USB Oscilloscope Probe Set
Pros
- No PC software needed — runs via USB-C as a USB scope directly
- 50MHz bandwidth sufficient for most digital signal debugging (I2C, SPI, UART)
- Compact enough to keep on the bench without dedicated scope space
- Includes 2 probes for comparing clock vs data simultaneously
- Works on Windows, Mac, and Linux without drivers
- Adds real capability at an impulse-buy price
Cons
- Not a replacement for a real oscilloscope — sample depth and trigger options limited
- USB bandwidth means slower waveform update rate than dedicated hardware
- No external trigger input
- Software UI is functional but not polished
Quick 861DW Hot Air Rework Station
Pros
- Stable airflow at low settings — critical for fine SMD rework without blowing components
- 700W heater recovers quickly after opening the gun nozzle
- Wide temperature range covers both low-temp paste and lead-free rework
- Includes 5 nozzle shapes for different component footprints
- Automatic sleep when handpiece holstered — extends element life
- Better-built than YIHUA/ATTEN alternatives in the same price band
Cons
- Display calibration can drift — verify with thermocouple on first use
- No iron channel — hot-air only, needs a separate soldering station
- Pump noise is audible in quiet environments
- Nozzle set is not labeled — requires reference card to identify shapes
Our Verdicts
FNIRSI P02 USB Oscilloscope Probe Set
The FNIRSI P02 is the best 'good enough' USB scope for a soldering bench. If you debug Arduino/ESP firmware, verify PWM signals, or check I2C traffic, it saves hours of print-statement debugging. Not a standalone scope replacement — a perfect $50 complement.
Quick 861DW Hot Air Rework Station
The Quick 861DW is the best standalone hot-air rework station under $150. Stable airflow and 700W heating make it genuinely useful for SMD removal and BGA work. Pair it with an FX-888D for a complete repair-tech bench.
