Mate bought one of those crap sanli`s.Do you know how you adjust the height? You remove EACH wheel and reset an insert for higher or lower!! True.That means any/every time you need to height adjust,you remove hubcap,split washer,wheel,spacer.Do your adjusment. Replace wheel.Now you do the other three wheels!! What were they thinking? Better still,why weren`t they thinking.Needless to say he returned the mower (after cutting all the lawn)and stupid as he was innitially, the shop gave him an upgraded model(Gardeners Choice) with normal height lever control, no questions asked. Haha.
