I used this kit for about a week before deciding to write this review. I work at a dealership and this kit works well for not scratching the rims. However, I had 2 of the 5 connectors disconnected when using a low torque electric shock, so I would use them as "special purpose only". rather than everyday industrial use. Nice product that looks and won't scratch discs but weak material that cracks and renders them unusable after prolonged use. 3/5 stars because now 2 sockets are broken. *Update* I used a 19mm socket on a Jeep JK Wrangler for the first time yesterday and split the tip. This time I didn't use a punch, just a medium crusher. 2/5 stars because I only have 2 out of 5 sockets now. I hate leaving bad reviews but it wastes my time (i.e. I lose money) as I have to go back to my toolbox to find another outlet and bang the round nut off the car/buy a new one.
