for most tools i totally agree, unless you're on about ratchets and torx bits which i've broken many and it's a pain having to go back to the shop, defo snap on when they break a few tiems and you get fed up.
also the halfords pro boxes/cabs are shite really, the industrial stuff however is spot on.
it's a shame they only make top and bottom boxes though as an intermediate one would be ideal to get more stuff in.
honestly best boxes for price, especially when sales are on, i blagged both top box and roll cab for £270 a few years back and never had a problem with build quality at all, to say regular retail is over £600 for them.
