My suggestion is to go with the Labradar. Mine has been hugely reliable, and i get perfect data with my 9mm, 223 and 308. The only time i ever miss a shot is if i forget to arm it. I love the new app and how it averages Power Factor on each shot, or i can see it on each shot. It did take them a while, but as a friend once told me, "do you want a rifle, or a rifle that shoots well". Its worth the money. When you think about it, if they had not told people the app was coming out then just deployed it nobody would be whining about it. I think you will be really happy with it. When i had questions they had great tech support by guys that actually use it.
