Anyone have one of these things? I have appoximately 2.75 acres and is looking to buying 3 of these guys to cut my yard.

They do not require a perimeter wire, can be scheduled to only cut when I am not there or the middle of the night. Seems like a no brainer.

My lot takes around 2.5 hours to cut. 3.5 if I am edging and trimming. 5.5 if I have to trim hedges and stuff.
So 2.5 hours a week time 24 cuts = 60 hours a year cutting grass. Those 24 cuts would cost me around $4800 dollars a year to have someone else do it, and that is if they even show up.

These would pay themselves off in one year, and I wouldn't have to even think about cutting the large areas of my yard.

Does anyone have one of these things?
