If you're looking for an affordable yet functional borescope, the GOLDEGGS Borescope is a solid choice. At around $30, it delivers decent performance for basic inspection tasks.

The 4.3-inch screen provides clear 1080P resolution, making it easy to see inside tight spaces like car engines or plumbing pipes. The built-in LED lights work surprisingly well in dark areas - I could clearly see oil leaks in my car's undercarriage without additional lighting.

What really stands out is the 16.5ft semi-rigid cable. It's long enough for most household and automotive uses, though I did find the tip could be more flexible when navigating sharp turns in pipes. The waterproof design came in handy when inspecting my bathroom plumbing.

The battery life is impressive - lasting through multiple inspection sessions without needing a recharge. The included accessories (hook, magnet, side mirror) add versatility, though I wish it had recording capability.

While not professional-grade, this borescope punches above its weight for DIYers and hobbyists. Just don't expect smartphone-level image quality - it's good enough to identify problems but won't win any photography awards.
