    Super durable, being carrying it everyday and competing with it and its on par with the dots I have from other ‘high end’ manufacturers

  2. Ben (verified owner)

    Shipping was fast. Product is as advertised. Distortion is not as bad as the first generation and seems to help with target focus. I’ve only fired about 600 rounds through it but zero is holding well. Buttons/controls are intuitive. At this point I would not hesitate to recommend this product. Excellent service from BTO as always.
