Link: IGN Reviews the C.T.R.L.i
IGN posts their review of the only iOS 8-compatible Bluetooth controller, and it isn’t a particularly positive one:
Andrew Hayward at IGN says:
[…] Switch to the d-pad, however, and a big issue emerges: there’s a small, but noticeable dead zone when you lightly tap in certain directions. A subtle press right or down often doesn’t register at all in the game, which can decimate precision-focused genres.
This matches my findings pretty closely. D-pads on MFi controllers are generally terrible, with the only decent one belonging to the Junglecat, which is currently MIA. While the Mad Catz’ d-pad isn’t quite as bad as the one on the MOGA Ace Power or Logitech PowerShell, it is certainly an off note. Still waiting for one of the MFi controller manufacturers to get this aspect right, or at least as right as Apple allows them to with their circle-shaped d-pad requirement.
