This dolly has allowed me to move so many things for my house move that would have either taken me longer with previous equipment or not been able to move at all. Example: Going in and out of exterior doors is so much easier with this wheel system, allowing me to go longer with less energy used by not having to fight lowering down entry steps with a load again and again as I load my trailer. Same thing with stairs and things like dressers, heavier stacks of boxes, etc. Some complain about turning being harder but honestly it's not that much more to do so. I would caution you on going down stairs with a load as once the wheels start flipping and basically walking down each step it will pick up speed if you allow it. Basically if you've got more than two steps be prepared for your load to drag you if you don't lean back and control the decent down the stairs. Yes, it really works and I wish I had bought one of these the first time vs a standard two wheel dolly. It doesn't replace an appliance dolly that includes a strap for those larger appliances, but close! I only now use this dolly and an appliance dolly while moving my household goods, or anything else tbh as you won't need anything else. Are there some special needs dollies? I'm sure there are a couple but this thing is awesome and if you've read this entire review you should by now be ordering it. I bought my own dolly and have not been reimbursed for anything for this review. What are you waiting for? Buy it and you'll be glad you did!
