Actually I reviewed the MagStik and I did have issues at first with hitting the diags but soon adjusted. I still use them today and have no problems at all hitting my mark.
There is a load of subjective material in your statements, something one has to watch out for when reviewing or commenting on controls. You may note I was very careful to frame my opinions as just that.
Aside from faulty craftsmanship, poor engineering, or poor manufacturing, if a stick is well made, whether or not you like it, or it is good for you, is VERY subjective. Height, ability to hit the diags, ball or bat, dustcover ontop or bottom, color, stiffness, throw, none of these can be considered good or bad overall unless there are extreme cases like you can't move the sick or whatever, they are all very much tied to personal taste, ability to adapt, and preference.
Always looking for a factual error to be fixed in reviews, but on the opinion and subjective side I too stand by anything I have written.
