Review on Cyful Adjustable Tapping Professional with Customizable Capacity by Aaron Franklin

Works great so far. As advertised, the larger size holds the 3/4" faucet perfectly. It appears to be made of quality materials. One handle (which does not operate the chuck) can be unscrewed, which is handy for storage. I didn't need this feature, so I used thread lock to prevent it from loosening when threading it in. Better than I expected from one of those fake Chinese companies.
