I agree when I had a slider, and I've had a couple. One was manual, and It was described as above. Very eratic. Bought one that moved with an electric motor. An old ant could have moved faster. Went to a non slide Reese which worked fine, until a guy working for me got in a tight spot trying to buy a coke and took out my rear window. Time I paid for that I could almost have paid for a Pullright superglide. I've now used one of them for about 6 years and it has worked flawless. Mine used slip plate and I have it tore down sanding and reapalying. Great hitch.
