You get what you pay for. Thule folds up in suitcase size in few secs. Easy to throw in boot of most small cars or store in corner of garage. I use towball version that can be fitted to car along with bikes in 2-3minutes with them secured with racks key locks. Press leveler and tilts to allow access to boot.
These small extra features make all difference when using regularly. Expensive yes but worth every penny. Friend bought rack half price and regrets it every time they use it.
With hitch mount racks make sure you use padlock pin to secure it to car. That also goes for hitches with towballs.
