I was really hoping this would be a good deal, but it didn't even last through the first workout. The D-ring that connects the strap to the harness couldn't endure with just 20 lbs of bumper plates on it, resulting the D-ring bending and disconnecting the strap from the harness. Not cool.
Second, the 2" post for the weight plates was not perfectly cylindrical and thus made it almost impossible to get regular bumper plates on the sled that had the 2" opening on them.
The product has been returned to Walmart and I'll be purchasing a REP pull sled.
