For about 20 years I made do with a small 12 piece Craftsman set. I needed a 6mm that I didn't have so I finally broke down and bought it. I had previously reviewed two sets of Harbor Freight's SAE and MM Pittsburgh, which cost about $90 each individually, and I wasn't entirely sure I'd like the quality. I read the reviews on this and as soon as it came out I knocked my bike frame out with this 6mm tap. I was very impressed with how easy the faucet worked, it didn't clog, but I also use the right technique. I love the nice metal case that comes with it. Some people didn't like the plastic pallets holding the faucets but I think they're ok. I think it's good that when the lid is closed and the case is picked up, you can be sure that nothing will be thrown around inside the case. Overall I am very happy with this set and I think you will be too. Note for EACH set of taps: Because the taps are carbon steel, they are generally a little brittle and can break in the hole if you don't go. often back and forth to clear the chips. It is important to avoid too much pressure when turning, especially with smaller faucets. If the faucet feels like it's stuck, it's time to turn it back on. Also use a light lubricant.
