Yea I bought one of these "Gems" and only slot 1 thru 3 work, as the relays on 4 thru 6 kept blowing....they would work for a while then then wouldn't work and fry. I tried to get help through Jammaboards and I asked if he has any extra relays to sell me, and he basically told me that he didn't as he needed any of the extra relays he had to fix the ones that were coming in from china brand new that weren't working.....so here i sit with a 3 in 1 instead....im not impressed with the quality and just waiting for the day the rest decide to die. So anyone that has theres still working, I am truly happy for you and hope that it continues to do so for a long time.
