I ordered a Malachite V-4 SDR radio receiver and it would not receive the standard AM broadcast band. I I warn all not to by active electronics from banggood.com. If it works your fine but if you have a problem your on your own for refunds. As a broadcast engineer this unit was clearly defective. Upon notifying Banggood.com they responded saying they have to have a video first which I supplied. Then they said they would get back with me after 24 hours. Heard nothing within 24hrs. After 70 hours I replied asking for a return and credit. They responded back in closing the ticket. This is poor customer service. If you are ordering connectors or parts your probably ok but acting electronic products be warned.
