Joe Rocket waterproof gloves- I think they made these backwards. Water gets in easily, but once wet, they never dry out.
Joe Rocket Alter Ego Pants- Cut way too short, and the "waterproof" liner was a heavy piece of rubber designed to do the exact opposite of goretex- prevent breathability but allow leakage.
Aerostich Stick-on Thermometer- I couldn't read it while the bike was running, and then it filled up with water. At least it was cheap!
Harbor Freight tire changer- I actually bought this piece of garbage and took it out of the box before realizing what a piece of junk it is. I took it back to Ching-chong Freight before attempting to use it. I know people love them, but maybe they never took the time to learn how to change a tire.
