Have used virtually ALL [repeat: ALL!] brands of TUBE (30, 40, even 50mm) RED DOTS over the years. ALL HAVE SAME PROB: variable adjust becomes loose, RED DOT goes out after each shot. Also: RED DOT is not 'absolute' like a Holo... "Floats" -hence, not nearly as accurate.
THIS SCOPE IS EXTREMELY, EXTREMELY ACCURATE!! SHOOTING Holes thru holes at 25yds - NEVER done that with my other 'TUBE' RED DOTS. WOW! EXTREMELY IMPRESSED!!!!
I place it 'AS ACCURATE' as EOTECHs which -as a Trainer- I shoot almost daily... at 1/3rd the Price!!! HELL YES, I RECOMMEND.
As for variable adjust: We'll see. Much firmer, smoother action than TUBE type, tho, can assure.
Pros: PRICE! EXTREMELY ACCURATE! Easier to see than an EOTECH!!
Cons: none so far.
