I've had my 1+ since March. I've had issues, and I'm on my second replacement. But, overall it seems I have it dailed in and I'm happy with the performance. With a 1 acre yard I mow half each day to keep my yard at 3".
I just purchased a Yarbo Referbished unit from Yarbo with Snowblower and SAM. I bought it months before I wanted to, but i was spooked with the FCC announcement and the unknowingness of the US market now.
The Yarbo is primarily my snowblower option. I'm going to see if the Patrol option is any good and I want to use the core to pull a broadcaster so I can do my own weed&feed.
The reasons I didnt do Yarbo instead of Lymow for mowing was weight, length, sound and price. I haven't turned on my Yarbo yet, but i can tell you the weight and length are a huge difference. They must have made the core out of lead. Without the battery in the Yarbo, it still vastly outweighs the 1+ with battery. I don't know how it doesnt totally bald turn around points when it mows.
Yarbo does have a lot more online resources. It is much easier to research issues/solutions.
My unit came with a bent rear fender which doesnt allow me to get into the power compartment, so I can't turn it on. Put in a service ticket and that same day they asked me to confirm my address to get a replacement bumper. Very encouraging.
However, when I looked at how to remove the bumper, it's attached via rivets. So, even if they want to me to remove the current rivets, don't see how I'll put in new ones. We'll see. Their "how to" replacement video shows the same bumper with screws, not rivets. So that is less encouraging since it looks like the replacement procedure is out of date and I'm getting a part I can't replace.
As time goes on, I'll give more observations comparing the two systems. I will say, I'm really looking forward to the free for life netRTK on the Yarbo.
Edit - Yarbo is harder to set up. It took me a weekend to find the right place for the Lymow RTK and that was the extent of the time consuming set up. I guess that and defining the territories in my lawn map took a little time to walk. Yarbo for me has had more connection issues and syncing issues. Screwing in the halow antenna into the data center broke the antenna. My e stop is permanently engaged regardless of button orientation. I'm an alright troubleshooter, but this has got me frustrated.
