Let me start by saying this little gadget has saved me hours of frustration. As someone who regularly inspects car engines and HVAC systems, the Hijoy borescope is a game-changer. The 5-inch IPS screen is shockingly clear - way better than squinting at my phone screen with cheaper WiFi models.

The articulating head is what really sets it apart. While it only bends in one direction (not two like some premium models), the 180-degree rotation lets me see cylinder walls and valves with ease. It takes some practice to maneuver, but after a few tries, I was navigating tight spaces like a pro.

I recently used it to inspect a clogged toilet (yes, glamorous work) and the waterproof cable held up perfectly. The 8 adjustable LEDs provided just enough light without creating glare on porcelain surfaces. The semi-rigid cable maintains its shape when you bend it - crucial when working in cramped areas.

Battery life hasn't been an issue during full workdays, and the USB-C charging means I can top it up with my phone charger. The included 32GB microSD card is a nice bonus for documenting inspections.

Is it perfect? No. The camera housing could be slightly smaller for tight HVAC registers, and the plastic body feels a bit cheap compared to $30k industrial models. But for this price point? Absolute steal. If you need reliable visual access to hard-to-reach places without breaking the bank, this borescope delivers where it counts.
