As a loader, I used too many mostly useless furniture trolleys with wheels that were too small and blocked because they didn't really have ball bearings. You can use the cheap $20, but you can send them straight to the landfill unless all your stuff weighs less than a Canadian dollar. Snap-Loc is heavy duty, has big wheels (although it might be worth getting an all-terrain Ferris wheel if you're navigating shaggy carpets), very good Snap-Loc ratchet hooks if you need to secure your load. . Definitely worth spending the extra money for something that actually works! Five stars!
