I got the pretty comprehensive lifeline kit about 2 years ago, some of it has lasted, some has been a bag'o'shite. The BB remover and crank extractor are two that have been no problem at all, and they've had a fair bit of use too! The worst piece of kit was the chain tool, pin broke on it's 4th or 5th use. Spoke keys are a bit crap too as they catch the rim with a sharp edge too easily.
Basically, anything that doesn't perform or breaks gets replaced with Park tools. This is mostly at the insistance of my other half who did furniture design and cabinet making at uni and applies the 'best you can afford' motto to tools.
