I have only used my slider once. However, the once I needed it, I really needed it. Manual is cheaper than the auto and leaves you with a trailer hitch others can hook up to (dealer, service, etc.). Round tube manual binds less than flat rail (supposedly). Keep it lubed. Even so they scream a little when shifting between front to rear position. As often as you need it, so whats a little noise.
