United States
I've ordered carbon tubes, plates and sandwiches from Dragon Plate many times to repair and maintain a sailboat. The materials have outstanding strength/weight, quality is excellent and deliveries have always been prompt.
Solidly built mower. Cuts great; accurately follows programmed boundaries. Unlike a previous robotic mower I had, it doesn't get stuck or turned upside down. Mounting RTK antenna to house 10 ft off ground with good view of sky is important; the first 2 places I tried had poor signal so I had to start all over again setting boundaries. Software is imperfect but workable. Expect to spend at least 5 hours with setup. Customer support is weak, according to other reviews.
Update June 22: The mower did a good job of cutting our lawn yesterday. It sometimes stopped for a while with a position information error when it was underneath trees which perhaps obscured its connection to satellites, but I am encouraged that this mower will function adequately. Previously: The email confirming delivery of my mower had a Fedex tracking link which was invalid. However, when I clicked the link back to my order, I reached a Fedex tracking number that was valid. And I did receive my Luba AWD 1000 June 14; I placed the order May 15.
