Query: Well worth the price

The first piece I got was slightly defective, one of the objective lenses unscrewed very easily. Further, the left and right were not aligned perfectly. Probably a refurbished piece.On the positive side, I got a free replacement, and the new one is in good shape. 8X-10X magnification is about the maximum one can go without using a tripod or some other stabilizer. This pair of nocks seems to have hit a good sweet spot in terms of specifications. It has a very clear picture, negligible color fringing, and the 50mm objective makes is very good for low-light viewing - focus on any patch of clear night sky, and you can see dozens of stars.I would have rated it 5 stars if my first shipment was not defective.
