Looks cool. I bought it purely for visual candy for my synthesizer.
Very happy with this product. It works as expected and the display looks good. They only complaint I have is that It’s very confusing to understand how to set it up. Once I finally figured it out it was great. Love that it can take an audio signal or use an internal microphone.

Really fun little audio toy! Better than some "professional" audio analyzer products I've tried
This is the best $50 I think I've ever spent on an audio device. It's VFD is beautiful and the motion is smooth just how you would want even a high end spectrum analyzer to operate. It has tons of options easily accessed, but don't lose the manual to recall the sequence needed for each option. It's also a clock when not in audio spectrum analyzer duty!

Great gizmo, TERRIBLE INSTRUCTIONS
The Spectrum Analyzer itself is pretty cool. Definitely worth the money. A bunch of capability. No regrets there… However, as almost everyone else has commented, the instructions are terrible. Not just a little confusing / incomplete, a lot. They’re really not very useful at all. I got through the configuration of the device as much by trial and error as I did anything else. I mean the instructions are bad enough that many people would want to avoid purchasing this device. Were a but more time and care taken with the instructions, this would be a 5 star review. As they stand, 3 stars is the best that I’d personally stand behind. Sorry Nobsound.

Decent display for the price
I was pleased with the quality of this display. The firmware could be a little better written, and the range settings could be better but for the price it’s pretty decent.

ya me llego y aun no marcan que ya se me entrego el pedido, lo que no me gusto es que vino maltratado, lo metieron en una caja sin envoltura y se ve se estuvo agitando llego con un boton desoldado y pines todos doblados ( los enderece como pude), lo probe, parece funciona bien.
