Works well, very quiet, and compact. Using it to mix 2 synthesizers in my music room. Would recommend. Actually just bought a second one for some other musical equipment; well worth the price. Seems well built with a metal case and feels solid.

Purchased this little unit to combine the audio output of two adjacent computers used for different purposes. everything was connected with high quality 3.5mm cables and I did replace the supplied power block with a higher quality one I had on hand of the same 12Vdc but 3A and quality made, it did make a difference in the maximum volume output as well as bass quality on my setup, and leads me to believe the 1A unit it came with may be slightly outmatched. All together its a good little unit but you might need a few extra things

Very poor circuitry, noisy preamp, useless as is, but a good cabinet to build a much better circuit into.

Simple and easy to plug in two inputs with one output. No noise or interference. I have two separate computers that share one set of speakers. Highly recommend.

It's a simple device, but works as advertised. The surprising thing is the very solid aluminum case. While finding a place to plug in the wall-wart is a nuisance, having a buffered mixer is a plus.IMO worth the money.

Using this with my 2 computers. It allows me to merge my audio and use one set of speakers. Works as intended, the volume knobs really help. Everything is well labeled and it's hard to use incorrectly. Casing is made out of metal and not easy to crush.

I needed to bring together two audio sources from two computers with one output. This solved the issue and gives me the control I needed.With a Y splitter on the connection I would get feedback and unpredictable volume changes. This was most prominent with computer reboots or when one would go to sleep. This is all gone now.I have been using this for 6 months without issue.
