Ed ~ My test binoculars have preformed very well, due no doubt to the nice build quality. The hinge and focusing system have not loosened or become misaligned and still feel as solid as when new. The Optical quality is very acceptable, with very long eye relief. The front objectives with standard blue MgF2 coating, and the use of BAK4 prisms adds up to give excellent images displaying very little colour cast, and which are clean and crisp in the central 80-90% area. The plastic and rubber body makes the binoculars reasonably easy and light to hold. These binoculars can still be purchased new via Ebay, although the price seems to have gone up to ~ £20
The bottom line: For inexpensive binoculars, these are highly recommended.
