Those things are crap. The buttons are too small. The joystick doesn't come up all the way so you find your knuckles continually brushing up the joystick circle.
Have you ever actually used one?
I have 2, and the stick is actually only about a half inch shorter than my Perfect 360s, and it is equally that much taller than the classic Nintendo sticks in my original Popeye.
Also... Your hand brushing the ring? How do you hold the joystick?
The only way that I can think that what you said would be a problem, is if you were all out gripping the thing with your full hand.
I definitely do not do that, or know anyone that does. I hold the stick with the side of my lower palm/wrist resting on the panel, while I manipulate the stick with only my thumb, index and middle fingers gripping it.
The only complaint I would actually have about them, is that they have analog buttons, which maybe makes a little more work for your fingers over the long haul.
Actually...
I just did a press test between them and the HAPP with cherries, and other than the nicer click feel of the HAPPs there was no real difference in force required to press them.
The Nintendo style buttons (they use micro switches, but have a lever with a roller on it that presses them) were MUCH easier to press on the other hand.
Anyway... If you are looking for a cheap and pretty compact arcade stick, they really aren't bad. I actually like them a lot better than the HORI sticks released for the 360, thanks to not having that riculously square action that the HORIs have.
[EDIT]
The HAPP buttons I tested were the vertical ones.
I just tested with some of my horizontal ones, and they are actually much easier to press, so that would be my only gripe about the reflex stick. Also the buttons on the reflex are smaller than standard, but I never actually found that to be a problem.
