As you have pointed out they are a load of crap and most of my time can be checking them and cleaning them.
Kind of given up on them now and will most likely discontinuing the Chinese ballnuts and standardizing on the better quality Gten range.
Its not just the swarf, but the tolerances of the balls, the crappy wipers and basic build quality.
