Summary: Talked to customer support TWICE and both times I got no helpful information on fixing it besides extremely basic stuff like "try pointing it at the router". I read other comments on this saying to not get it, but I thought my case would be different since I am only a couple rooms away from the router. It may work better on other devices but for a desktop wireless card, it worked terrible.
Pros: None really.
Cons: The antenna is nearly a foot long and is replacing 2 2dBi antennas on my TP-Link wireless card. These gave me half the signal strength and speed as the 2dBi! I don't know if the wireless card (which is also brand new) is giving them enough power to operate or what but for an 8dBi antenna that is 3x the size, shouldn't it give you better performance?
Excerpt: вкрутил в д-линк dap-1155 у которого антенна 2дби. без антенны точка перестала ловиться тоесть не просто так торчит. поставил, проверил - разницы НИКАКОЙ. ни в приеме ни в передаче. хорошо что стоит всего 60грн.
