I'd been after one of these for a while as I'm a keen birder but have had increasing neck and back problems, not helped by carrying the equivalent of a bag of sugar on a neck strap for extended periods of time. This is the basic bargain version harness. The more upmarket ones have elasticated straps but I really don't see that that would make a terrific difference and this one is almost half the price. It works and that's the main thing - you hardly notice you're wearing bins, they don't bounce around so much and the quick release means it's easy to take the bins off the harness if, for eg.you're in a hide for a while - just remember to clip them back on before you leave!
