I ordered this and the day I recieved it I cleared out a bunch of heavy stuff that had been cluttering up my yard, but was too heavy for me to lift by myself. I used it mostly in wheel barrow mode, and used the arms to slide right under a large kid's battery operated atv and move it. I tried out the net for large rocks and discovered a few things about it. The rock must be perfectly balanced or it will flip out of the net. If the ground is uneven and you try to move too fast, it will flip out of the net. I moved the more evenly shaped rocks with the net, but the easiest way was in dolly mode. Even the large irregularly shaped ones could be rolled onto the dolly and moved. I have not used the trash bag holder or barrel holder, and mine did not come with the seat. It will always be ready for use because the tires will not go flat. My husband says the handles are too low for him in wheelbarrow mode when he moved a bunch of sod, but I think if he'd put the dolly base down he could have tilted it up more with no worry about sod sliding off.
I bought my house two years ago and began creating my wish list - I bought the WORX edger/trimmer/mower and I had the Aerocart on my list. I finally bought the Aerocart and I love it! Very easy to assemble and I can't wait to use it this fall when I redesign my flower beds!!
