Vest covered most of it, but I'll add my zwei pfennigs:
- Other than the battery hump on the back, they're the same shape and just as comfy as a normal controller.
- The batteries last a long, long time. I only change mine a couple times a year and I try to sneak in 10+ hours a week of play(withmyself) time.
- The receiver acts like a tap (a switch on the controller sets which one of the five each controller is), but it can be used as a single controller on a wired tap if necessary.
- The only other wireless controller I know of that was made specifically for the Turbob is the Acemore Freedom-16, which is two button and rather shitty. It has it's own receiver and is not compatible with the first party pads at all.
