Do what its supposed to, seems quite sturdy. As it features a phono input you can just use it as a low quality/low price amp and plug it directly to your speakers. The stated dimensions (product information) are in inches and not in centimeters.
Now I have complete control of everything! I am a 10 year old that has speakers, microphones, amplifiers, lasers, stage lights and a mixing desk to go with the lights. This is the only thing left I needed to make a fully functioning disco!
