I acquired this unit cheap and broke at a ham swap meet. The mounting screws for the power resistor were loose and rattling around in the case, but the resistor element tested good when the contact surfaces were cleaned. I bent the mounting clips to clamp it better, gently cleaned the contact ends with a rag and some alcohol, reassembled it, and voila!
This is small enough to carry in my tool case when doing HF transmitter evaluation on site. Quality is what you would expect for the price. I never cease to be amazed when people give bad reviews to something so useful at an affordable price. I observed no blemishes in the paint. Maybe they upgraded the paint process. Not lab grade, but perfect for quick checks in the field. I am skeptical about the UHF specs due to lead lengths and mechanical issues, but I do not use it that way.
