This is my SECOND trailer hitch bike rack. The first was another brand at 1/4 of the price. When you pay for a cheap product, that is just what you get. Returned it before I ever used it. The Thule name is highly trusted for good reason. This bike rack is EASIER to mount on my trailer hitch than it is to change a light bulb. Durable, light weight while being very sturdy, bikes do not wobble around, comes with trailer hitch lock core, and lock down arms are lock core ready. I like the platform style much better than the post and arm style for easy loading, stability, and all around convenience.
