I have yet to use the taps and dies but on receipt and checking them out-
The good:
A very comprehensive set which will cover all my metric thread needs.
Case to hold all the items in.
The Not so good:
The dies had a lot of swarf left in them - will sadly really need a decent clean and flush before use.
The Tap&Die holder handle threads are not a quality tight smooth fit, rather loose, could be better.
Some items are a very tight fit (too tight) a fit in the case, good to not have things loose, but not so good when they are difficult to extract.
Not sure what the "The storage case comes with pearl cotton cushioning, providing excellent shock absorption and cushioning properties" specification is about, I found no such material in the case holder slots, just plain plastic.
