Budget friendly red dot with pros & cons - Vortex Crossfire II 1x22 mm 2 MOA Reflex Red Dot Sight

When I recieved my package and unboxed this red dot I went ahead and compared to it my Romeo 5 and I like the quality of the glass and red dot compared to the Romeo but don't like that it's slightly taller than the Romeo cause I can't run my rear flip up sight I have but it does with the Romeo. I tried changing the mount that the Romeo has with the Vortex but it still didn't help but will still keep for another weapon. The brightness levels are not that great in indoors you can barely see the dot in 5th setting at night and 6 or 7 in the day depending on how bright it is so I keep at 8 no matter what since 9-11 are way too bright of settings,btw the Romeo has a similar problem but has a better option of turning on/off and adjusting brightness. The quality of the Vortex looks just as good as the Romeo I think they are made of similar material but I might be wrong. Zeroing this red dot was easy it took about 3-4 shots and am happy with this purchase since you do get the lifetime warranty so will recommend. Ps have extra batteries jic you get a doa
