Review on Danco 80439 Bibb Seat Wrench by Josh Fox

Machining and coating are inaccurate and rough. This is an inexpensive tool but probably suitable for non-professional use. The smallest square dimension was about 0.5mm larger than the size of Danco's own bib on their 9B-3C stem (Sayco style). I ended up scraping off the Dremel grindstone a bit. At first I tried just sticking a flat head screwdriver in, but ended up needing this tool to pry out the 50 year old stems. Gave it 3 stars as despite the issues it still saved my bacon.
