The seller sent in 30 minutes and reached growth. region for 20 days. took 8x (for soldering), the focal length correspond to ~ 100-130mm. Made of aluminum alloy, 3 modes of illumination (as it seems to me-normal, warm and cold) and 3 modes of brightness. Cord approximately 1,5 meters. The lens is clear stump is not made of glass, but at first glance it is made soundly. Packed is not bad, but in my case the box is crumpled, but with a lens and illumination all in The Breakthrough. the price ratio, the quality is normal, in other stores is much more expensive, with this quality. the seller and the product, I recommend it!
