Although not bought from CBS, I have had this tool for about 5 years, and cannot fault it. I couldn't count the amount of brake and clutch systems I have done with this tool over the years with no noticeable change to the high quality of single or double flare produced.
Two recommendations I will make is to invest in a upto 16mm pipe cutter which is small enough to fit inside the box with the tool.
And a small plastic bag to put the grease and taps etc into. Keeps everything tidy, stops the grease you put on the punch getting on the handle and tool in storage.
Requires a 16mm spanner or deep socket and a 10mm spanner/socket.
Easy to press flares on or off the vehicle.
