The VU-meters looks and works very well out of box, except the back light. The producer made a mistake there and put the resistors with wrong values, that big resistors from the board have 430 ohms instead of, i guess, like ~43 ohms. I replaced the original resistors with 47 ohms / 5 watts ones (they are oversized at that wattage as they barely get warm, so i guess that you can use 1 or 2 watts resistors without any excesive overheating), and they light up just right now. The sensitivity of for the level of signal is perfect for what i need (input from an headphones amplifier), with the variable resistors tuned around middle position. Good product and good value for the money, with just that small downside of resistors fix. Overall i am very satisfied!

Received in good order, although it took a little longer to come. Done some modifications to the board. Changed the resistors of VU meter lights to 47 ohms (5 watts) for brighter lighting, mounted them off-board and connected a on/off switch for VU lights. Removed the original potentiometers and mounted new ones on the chassis for easy adjustments. Response of the VU meters were quite acceptable, output was from a sound card. The glow from the VU meter lights was nice in the dark.
