Weaknesses:
I begin with the most disturbing: it is common that the lever locks the direction (left or right) either with directional pad or analog stick (probably related to the wireless connection problem)
Bad wireless reception, being less than one meter, if you are not right in front of the dongle, but too far out, you lose the signal.
Supposedly using technology from Logitech Unifying, yet I already have a wireless keyboard of the same brand, and yet I have to use the dongle for this joypad in order to be recognized
Response times to review, if you play Super Street Fighter or Guacamelee (games that I lack with this joypad), it could go fairly hysterical! : Þ
Trappe battery compartment that seems fragile.
