all i know is the rx fired a bit slower than the dna reuleaux and the yihi sx mini...the download was available so i did it and the delay is gone and the display seems brighter and crisper...the delay didnt bother me, but, im a happy camper...enjoy the holidays...got any special plansHahaha, you guys will be annoyed by the KOOPOR DELAY 0.02 seconds
