Quoted from luckymoey:I have a pair of the forearm ones and they work well. Would still recommend keeping the machine in the box and using an appliance dolly.
Get help and a dolly, ideally an appliance dolly. I have some of those straps and they are ok at best for hauling stuff in a straight line; going up and down steps with them is a nightmare.
Unbox game, secure to dolly, slowly and carefully two man move up the steps.
