It works like a grigri but is a third the price. Takes a few belays to find out how it works, but when you do it makes perfect since. Its really easy to let rope out when lead climbing but it just as easy to take rope in when you are top roping someone. If you want an assisted locking device that doesn't cost much and it light weight then buy this device.
