Been using this for the last 3 days now and I must say it works really well as long as you know where to place your crosshair, tapping w vandal is so ez from distance and marschal/op is crazy I never miss a shot using it. Took me few hours to figure out the settings and what works best for me, apparently been ud for 3+ years and still going strong. Would recommend this 9/10 for sure.
