For thermal borescope visual inspection, the first choice comes down to how far you need to look. The 1M KERUI USB Borescope is a low-cost Android-phone probe, while the 32ft LED Handheld Industrial Endoscope is a standalone unit with its own screen. Both are new units made in China, but they target completely different jobs.
Quick verdict
If your inspection target is close and you already work on Android, the KERUI is the sensible budget pick. If you need to follow a long, awkward path and want a dedicated display, the Handheld Endoscope is the stronger tool. The higher-priced unit costs about $21 more, and that money buys extra reach, a sharper camera, and a built-in screen.

Product notes
1M KERUI USB Borescope
The KERUI is the compact option for quick looks around the house or shop. You connect it to an Android phone, and your phone becomes the viewing screen, so you don't need a separate monitor. The tip is narrow enough to fit into small gaps, and the IP67 waterproof rating gives you confidence in damp areas. The main limitation is that it depends on Android USB OTG support, and its short cable keeps inspection targets close to you. That makes it a great first borescope for simple visual checks, not for reaching deep into a long pipe or duct.
32ft LED Handheld Industrial Endoscope
The 32ft Handheld Endoscope is the serious tool when your inspection path goes deep. The built-in LCD display means you don't need a phone, and the 1920P camera delivers a much more detailed image than the 640×480 sensor on the KERUI. It also has adjustable LED lights to manage shadows at distance. The catch is the 8mm probe, which makes it a little less likely to squeeze into the very smallest openings, and the higher cost. If your job involves repeated inspections of long, straight runs, the LCD display makes reading results easy. This is the one that pays off.
Final choice by use case
Choose the 1M KERUI USB Borescope when you want a low-cost, phone-based tool for quick close-up inspections on Android. Choose the 32ft LED Handheld Industrial Endoscope when you need maximum reach, a standalone screen, and a sharper image for longer borescope runs.
