My initial analysis of the swfa 1-4. Glass is clear enough for any ranges you would actually use a 1-4. I would say its on par with most of the glass coming out of japan. Eye relief is decent, definitely better than any of the other scopes I've tried in this price range. The brightness of the image isn't as good as say the trijicon tr24 but definitely on par with scopes in this price range. The reticle is really precise and the easy ranging negates the need for any math that you would use for a mill system making it fast to figure out a firing solution. However i did notice that the reticle is a little bit hard to pick up especially at speed when you are trying to be fast. This I believe is a byproduct of the reticle being rather busy and the lack of illumination (ill get to that in a bit) The turrets click positively, and firmly. I wouldn't be worried about accidentally bumping the turrets and loosing my zero. And the turrets are probably better than the swfa ss 3-15, even better than some sub 1000$ vortex stuff I've tried. I initially had some trouble setting the proper focus and getting the 1x to look right. At first everything was way smaller appearing through the scope. This is big problem with lower end glass, because if the image doesn't look the same through the scope as it does with the naked eye it slows you down considerably, especially when practicing snap shots inside of 20 yards. but after messing with it i got it pretty close to looking right. I found the illumination is pretty much unusable for everything except maybe inside of a house with artificial lighting. But outside even with overcast sky it really doesn't have enough juice to be picked up easily. The unit includes 2 batteries and has a place in the battery cap to store them. they include 3 different cat tails, and that save you from having to spend more on a cat tail. Overall good scope for the money, and you would be hard pressed to do better for 400$
