The Nintendo DS Rumble Pak was initially met with harsh criticism, as CNET pointed out the limited number of games compatible with the the accessory, at the time only four were compatible. IGN also pointed out the annoying "squealing noise" or "electronic chirp" that the device made when rumbling, and stated that "Good thing it's free, because at this point we wouldn't bother buying it as an extra" as they felt it was "broken".
