My experience from China Hifi is surprisingly a good one.
I ordered an amp - yes the “postage” was expensive but the amp wasn’t so basically I took the whole costs as a cost for the amp. Worked out £550 inc customs in the end.
We ordered the beginning of Feb and after a week it still hadn’t been sent so I emailed asking what the issue was. He replied the same day to say that it was Chinese New Year and everything shuts down but he could send one from Europe if that was acceptable. I said it was and it was posted. It didn’t make it past Germany - it just never made it to the UK. After two weeks of waiting for it I emailed to which once again they replied straight away and between us we came to the conclusion it was lost and they said they would send another on the provision I send the old one back if it arrives - I said they had to pay the postage if they wanted it back and they agreed.
The second one was sent and this time it arrived. It was extremely well packaged and the amp is well made and all works fantastic. Do I recommend them? Yes I do.
