    Pretty good amplifier for such a low price..good sound quality if paired with good quality speakers..one tip you can use a 5w speaker with it if you just use one channel and connect the right and left channel to just one channel on the amplifier..it works pretty well

    First of all thank you Robu, this is my first purchase from this website, on 29th may and product is delivered within 5 days or less. Then after one week leaving this alone, On Thursday i started working on this module, I done the all the necessary things which the module is required that one lead cable which connects to smartphone and one is data cable which provide 5V to this board and also connected two speakers with it. After finishing all the things then it’s testing time ? then I plug the data cable in adaptor and adaptor in electric socket, and connect the lead to the smartphone and switch on the power supply and play the song, the output of sound quality is awesome and i impressed with this module.
    last thing which is at 90% or 100% bass or sound quality is not good means not very clear but all other things are very good.
    Again ? Thanks Robu only one suggestion please remove shipping charges. Hope helpful for u.
