Lymow One does a good job so far.
Received unit last September. The mower was perfect until I started getting updates. I would disconnect the battery and wait a few minutes and it would straighten out. Once I had to delete the app and reload and my maps came back. The side discharged would stop up before it mowed 30 feet. With mulch setup it seemed the battery wouldn't last as long and the blade motor on at least one side would be stuck because grass would dry around it the next time I went out to mow. Cleaned it off and worked fine. It didn't have grass under it except around the motor. I took off the mulch and side discharge pieces along with the bracket with the square hole for the grass to blow out. I truly believe it cuts better and throws the grass without stopping up. The screens have not stopped completely up like they used to since then. This allows air to flow over the motors and helps keeps them from over heating besides blowing the grass out. I started out going to slow, 1.6 speed and blade height 4. I have switched to 2.6 for speed, blade speed standard and height 2.6. So far the mower is doing a good job. I did have the problem with charging so I ordered another battery which came with a charge cable. I have both batteries charged before I start to mow and when one gets low I put the other one in and I can mow a acre and a half in about 7 hours. I put the low battery on charge and before the other needs to be replace it will be charged. Also noticed the battery last longer with the way I have my settings. Hope some of this information will help others.
