True quality and craftsmanship can be had with the purchase of this spark plug socket. Very sturdy, I've used it with low torque electric impact ratchets for speedy removal and insertion of plugs and it works great. The non magnetic metal fingers inside hold the spark plug firmly but gently so it won't fall out nor get broken, it's really the best for these new turbo spark plugs that are quite fragile. Never had a problem! Not to mention Hazet is an oem for Mercedes Benz brand tools, I have coworkers at Mercedes Benz who have the MB brand spark plug sockets and they say Hazet on them but they have a MB part number and the 3-pointed star. So truly the same! The universal joint works well and the stiffness of the joints can be adjusted with a torx driver, even the worst spark plugs come out easier with this tool! Seriously recommend this tool for professionals, and I still recommend it even if you are buying it to work on your own car once every few years.
