I bought four of these a few years ago. Two of them have failed (broken retraction spring; lost axle retention clip). The other two are still going strong. They are extremely handy, so I bought four more recently. My only quibble with them is that the strap is frequently just a wee bit short. A selection of short "choker slings" helps make up the difference (I move a lot of furniture for my wife's "antiques" racket).
