A real holographic sight has a completely different imaging principle from the red dot and with high light transmittance and no matter from which Angle will not see light leakage and reflection, but this seems different. I'm not sure the reason is on It's mode or something else, but the image looks a little bit yellow. And it didn't show the sight in other different angle. If you want a real holographic sight i don't really recommend you buy this on aliexpress. I will prefer to buy the eotech on “tatical kit” or
their official website. But for most player, a good holo sight clone is enough.
