The few taps and dies I have used have preformed as expected. They seem to be of good quality steel and have cut good threads. The adjustable tap wrenches feel cheap and the threads are very loose. The included screw extractor set is a nice addition but I found the largest extractor wasn't hardened as it deformed when trying to remove a burr in a nut. Using a hand file it cut right into it. I bought the set to have all the sizes organized in one case but I found each time I opened it everything was all jumbled together. 6 of the taps always fell out so I used silicone tape to give them a tighter fit in their slots. The die set was packaged in bubble wrap in a box and I cut the bubble wrap using the case as a template. This placed over the dies when the case is closed keeps them in their respected positions. Now it can be opened and everything is where it belongs. As I have only used maybe 6 of the taps and 2 of the dies I've had limited use and time will tell if the rest are of good quality.
