This is a subtle difference, and a lot of teams aren't going to realize why these gears aren't working with their current stock when they arrive, or if forced together, causing premature wear. I would wager that a significant number of students currently designing mechanisms have never heard of pressure angle because standardization has meant they've never had to learn about it for FRC purposes, and will assume that these are compatible with AM/Vex gears they already have. Which is a shame, because the price and selection is wonderful, and would help make custom geared systems more accessible to many teams.
Ohh, you wanted CompatibleGears, not CheapGears. Easy mistake, happens all the time.
