product come in good condition and good quality after use it for couple hours.
I received the package in very good condition, the contents are as described and fully operational. Thank you.
Just assembled it (very easy) and have just connected it to my speakers. Connection via Bluetooth very easy and am now listening to music and it sounds very good for the price. Very happy with it. Will try a bit of valve swapping over the next few months.
I ordered out of curiosity. It works. Nothing extra, no point in my opinion. Another unnecessary order :)
