I don't write reviews but this thing is far too cool to go without. For anyone who loves electronics, particularly good stereos, this is a must have.Assembly is relatively easy. Just look at the picture and you'll be fine.Mic is the default setting so if you're hooking it up to your receiver, you'll have to go into the programs and change that. Easy too.Absolutely love it. Bought a cheaper piece of crap and regretted that. Spend the money and get this one!

My only con was that UPS "lost" my package so the delivery date was about 8 days after the guaranteed delivery date from Amazon, but still gave it 5 stars because this device is amazing.Assembly was as easy as the YouTube video but you have to ensure that the back lexan piece is oriented correctly so that it fits flush on the back against the PCB.I connected the analyser to the 1/8" audio out connector from my Samgung's TV OneConnect box, while the main TV output is feed via digital optical output to my Polk SurroundBar and ran a couple EDM videos off YouTube to check it. The analyser provides a great "wow" effect and visualisations.Also ran an audio test sweep video from YouTube to check the response and it seemed pretty accurate.

Solid build. Looks and works great. Needs partial assembly. Assembly insructions non-existent, but with a bit of trial & error and common sense, easily accomplished. Set up insructructions murky, unclear and disorganized. Wish manufacturers would learn to write clear insructions.

Darn segments have started to fizzle out after a few weeks. Also its a nightmare to program if you happen to press the wrong button. Hours to get back to stock config.

it took about a minute to put together and I plugged it in and it started working right away and all the displays work, the mic is very sensitive, it picks up the traffic when the window of the room is open.

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.

Works well made well. Mine came with a black PCB which was a nice touch. Works great in my car and at my computer.

Great little unit. Customer service is was very quick to reply and ship. This was scheduled to arrive in August, however arrived much earlier. My only concern is the power input into the unit seems like it could snap if you don't push the power source slowly. Other than that, lots of features just wish it came in a nice complete housing unit to dress it up. The only design change would be to put the power and audio connections on the back vs the side!
