Euro optic is one of the most legit optics seller online. The blinking can be annoying though. You get a sturdy well built optic with a company that stands by their product like no other.
Easy attach and detach. Comes with an extra battery. The cover is loose but for how inexpensive this item is i'm not holding that against it.
Mostly unreliable reviews. Do more research before proceeding
