Pros & Cons
Pros
- 7.5-inch IPS screen — no laptop required for live viewing or capture
- Flexible gooseneck arm provides excellent positioning for PCB inspection
- 7MP camera delivers sharp images at working magnifications for SMD work
- Continuous magnification dial (10x–220x) — no discrete step jumps
- Captures still images and video directly to SD card
Cons
- 7-inch screen is small for detailed specimen study — a monitor out gives better results
- Zoom range tops out at 220x — not suitable for high-magnification biology
- USB output mirrors the screen but doesn't provide a separate clean feed
- Software (Windows app) is basic and rarely updated
