A decent borescope for its price, but mine came with the camera tilted relative to the articulation plane. Customer service offered a discount but could not say whether this defect was field-repairable. Eventually I decided to take a risk and repaired it myself.
Missing some features that would be easy to implement:
- portrait-landscape switch
- swiveling (and not only tilting) display - sometimes it's more comfortable to have the display in the same plane as the steering knob
- a hard sheath for the snake tube - for some tasks the tube needs to be rigid
- "condoms" to protect the tip part against dirt, aggressive substances, etc.
