Rated 5.0 out of 5.0 by Robomower is worth it !! When I first got my Robomower RL850 I was a bit skeptical but my wife wanted to give it a try so, over the course of about a week, I spent about 6 hours laying out and tacking down the perimeter wire and staking the zone power things. When that was finally done, I saw the fruits of my efforts. The robomower works great. I stick it in a zone and let it "do it's thing" while I'm doing something I don't usually have time for. Now, I still have to trim the fence and edge the sidewalk but that takes all of about 35 minutes. Long and short: If you're in the market for a new mower, the Robomower should be on your short=list. - - -> Note: Landscape staples, readily available at Home Depot, are cheaper and easier to use that the green stakes from Friendly Robotics). mw p.s. Watching it maneuver around the yard is a great conversation starter with all of the neighbors. July 10, 2012
Rated 5.0 out of 5.0 by Very good buy Setting the stakes was time consuming but the fact that I can run it and do other yard work is a HUGE plus. May 21, 2013
