Excellent pair of pocket sized compact waterproof binoculars at a sensible price. Only gripe I have (and it is a small one) otherwise it would have got five stars. The focusing wheel is very sensitive compared to my larger binoculars. But having said that it stays where you focus and doesn't wonder, with a very good build quality. Vision is pin sharp and bright for the size and price bracket, just the job for trekking/walking etc. So if can live with sensitive focusing, buy them they're really very good for around the hundred pound mark, I would say as good as pairs twice the price. By the way, I have bought numerous bits of equipment from Wilkinson cameras and never been disappointed. Tried and tested, long established. Speaks for itself.
