The quality is ... 'adequate' - OK enough for the occasional-use-in-the-garage but not for setting up as a Bike Mechanic, if you see what I mean.
The chain tool on mine broke after a few uses/abuses , so I have re[placed it with a better one. Chain whip is still Ok - and I've used it 20 or so times. The cassette tool is one I have treated with great care and is still surviving. Other bits, like hub spanners, pedal removing spanners/wrenches - no problem - but bear in mind that the metal used in the making of these tools is not going to be the hardest our there, so care need to be taken that you don't 'round' the spanners etc when applying some grunt !
If it is your first venture into bike-specific tools, then I would say they are a reasonable place to start. I still haven't used all of them yet .. still trying to work out what some of them are !
