so far, i really like them. my panel has only been functional for about 2 weeks now, but i am very happy with them. i bought the longer shafts, medium springs, and octagonal restrictors. however i really didnt' like the feel of the restrictor, so i took it back off. i was a little concerned at first by the lack of clicking, however i seem to be adjusting just fine. i am not a fighting game expert...far from it...however i found that i can pull off dragon punches in street fighter much easier with the u360 than i could with my x-arcade sticks. they work pretty well as a 4 way stick also. yeah..they lack the physical restriction of a good 4way stick, but they feel good and respond very well. i haven't noticed any drop in my scores in pacman or donkey kong since switching from a dedicated 4 way to the u360s.
i went back and forth a long time tryign to decide if i should spend the money for the u360s...looking back, i'm glad i did. my panel is only 12x30" so i didnt have alot of room. i really wanted a trackball, and it would have been really crowded tryign to fit a dedicated 4 way stick in there yet also...
