Decent product for a good price. Only concern was with the length of the speaker wires, need to be 1/2 inch longer. I was able to use the supplied wire but it was a difficult process! Hooked up the unit to the ear phone jack and USB port on my laptop, played a few tunes though it, very nice sound quality! Good starter practice for SMT parts as the two power amps are surface mount. Overall, highly recommend.
