I bought one of those from that ebay seller . It was DOA! I tested my rkcstr driver it was putting out 100mA no prob . I had correct pin out and aixis module for heat sink......NADA! I e-mailed the guy and told him what I thought. All he had to say is "When did you buy it?"
I will never buy anything like this for more money from a dealer I dont know again! I just felt it was worth checking out .
Mine arrived in working order. wrapped in about 3 ft of tinfoil then a strip of bubble wrap in an envelope. Powered up fine though. Can't say as to how powerful though w/o a meter, but it's pretty strong.

You guys know Scopeguy20 sells GGW sleds at a very reasonable price, why are you going to an unknown to buy them ? when I spend my money I try to spend it in my neighborhood. have a good day !
