Query: not even good for paperweight

I recently purchased these "tools" and my findings for the dies are: the cutting jaws BEND when trying to thread ALUMINUM. This happend to 3 separate dies: 1/4-20, 3/8-16, and 10-32. These are NOT alloy steel, but cheap carbon steel, not heat treated but coated to look like they're annodized. Upon inspection, the die threads aren't even deburred. I'm afraid to try the taps because I'm sure they'll either snap off in my parts or bend.Overall impression: typical of Great Neck tools - minimally acceptable at best, dangerous to use as a primary tool. Better to only buy quality taps and dies as you need them or deal with a reputable company's products. The only parts of the tool set I use are the tool holders.
