Diamond 980000N High Power Wireless Adapter USB WiFi card

Diamond 980000N High Gain Powerful 38DBI 3800mw is using ralink wireless rtl3070 chips
rtl3070 dose support inject and monitor mode … but what about diamond !!!
with this adapter you can get a huge list of Wifi access point, the signal is stronger then many other cards on the market, but it’s not the best you can get,
I got this card just to check it and after testing it, no i would never buy it or suggester it to a friend…
