Magnets are great. They help loads. I've got one clone with a magnet and one without. But I've also found that fiddling with the springs in the switch can help almost as much. They don't always come from the factory perfectly seated. Have a go at them. With enough spring fiddling, my clone without the magnets works almost as well as my clone with the magnets. Also make sure that the connection plate is completely screwed in. A loose plate will make the switch crunchy for sure. I have to adjust mine fairly frequently.
