Although i have said good quality, i would say it is half good value.... I bent the 6mm key with my first use...and yes it was perfectly aligned, but could not handle the pressure i was applying to the pedal... The 8mm key should be stronger but as yet untested
This tool does the job and looks like the socket oils be changed if it ever needed to be which is handy - I’ll only be using a few times a year so is perfect for me
