Needed to change some alternator pulleys on my private car. I'm sure if this tool had to be used daily it would wear out quickly but I've used it twice in 12 months and it's still fine. For the price, it's a quarter of the cost of an hour's work in a shop to do the same job. What's the difference if it's not snap-on? It does its job and saves me $$$. At my old job, the new mechanics had nice shiny tool cabinets full of socket tools. Experienced mechanics at ASE Diesel had cupboards full of port cargo tools. What does that tell you?
