High value, high quality
I can't provide a long-term analysis, but this optic provides an acceptable value on the face of it especially if you get it on-sale. Feel and finish is high for the price. Included packaging and accessories leads me to believe this manufacturer values their customers' experience. I would definitely buy again.
