I used mine for the first time after buying it and trying to keep it covered a year. Rand it continuously for abot six or seven days with no problems other than blade sharpening. I used the original blades sharpened while having the american made and installed ones sharpened. I will buy a new set of quality blades to go with the ones wod max supplies on the unit and throw the old Chinese ones away.
My advice is not to judge products just because they come from china. Just like in the USA, there are good and bad. So far wood max has been very good and I would say it has almost paid for itself in the first two weeks it has been in use vs. hiring a tree service or landscape co.
Anyone who has been to China lately has had a rude awakening, the bicycles are almost gone, and the state of advancement in their larger cities has to be seen to believed. Shanghai is at least 25 years ahead of us in that regard. That city's population is almost the size of Canada- 30,000,000. Not a comparison, just a little known fun fact. They are moving into agriculture also, which is not a good thing for the current leaders in that market....
