1. Product: I have 2 RD D9's forsale. They are still like new now with MAYBE a total of a hour play time on them. The strongest and most favorite 5k board I got to play with. Tested these 2 against 2 500.1's and FIRST test was .6 higher that 500.1's. Didnt get any more time to test more so im sure there was more in it //content.invisioncic.com/y282845/emoticons/thumbsup.gif.3287b36ca96645a13a43aff531f37f02.gif
