TTI Tools are either rebadged sidchrome, Bahco, Snap-on or Stanley. Good mate is the head sales manager for TTI @ Wingfield, so straight from the horses mouth.
I bought a TTI Ratchet ringy set to replace my old busted sidchrome set and they were Identical, inc. the box they came in.. And my TTI Hammers are exactly the same as my old man's stanley hammers.
And +1 for craig @ Just JDM Spares, so easy to deal with.
Either way, TTI Is awesome stuff for the price. Seeing as it's just rebadged name brand stuff.
