Review on Ultimate Bike Maintenance Tool: BW Bicycles Cassette Lockring Removal Tool with Handle - Center Guide Pin Included for Shimano, Suntour, Sunrace, Sram XD Cassettes by Brian Samuel

The Cassette Retaining Ring Tool is a must have tool for any home bike mechanic, especially now that disc brake disc locking rings use the same keys. I will go with Park tools if there is a noticeable difference in functionality and/or durability. But when it comes to cartridge snap ring tools, Park either goes halfway with the FR-5.2G (which requires an extra large wrench to turn) or overdoes it with the unnecessarily beautiful FR-5.2H. This separates the difference in price and build cleanly. It's just as functional and feels just as reliable as the FR-5.2H, but at a third of the price. If you really like shiny things, get Park. Otherwise this is all you need.
