Never bought supatool stuff..... but don't really trust stuff that you can buy from 'super cheap auto'
Sidchrome usually good, but have gone thro heaps of there new ratchets, tho they are covered by warranty, the process took 3 months and the replacement one is stuffed already after 3 wks.
Got a heap of CGL stuff.... spanners and socket sets are good.... but screwdriver sets are rubbish.
