i thought the specs were pretty good for the price , then i called him to get some info ,he couldn t tell me much about his own product
needless to say i payed a few bucks more and bought geckos , they are well respected and from what i ve read over time as far as the support they have earned that respect

He does not know anything about it becasue it is not thier product.
This driver is the same as the MSD980 and is a very good driver, and very easy to use.

hi that link http://www.kelinginc.net/StepperMotorDriver.html


there using gecko drivers also

cheers

Did the same as dertsap. Thought they were a heck of a deal, then thought about it. Hmmm..... I know Gecko is good, and I know they will work. Twice the price of the smaller Keling drive. Almost the same price of the larger drive. And no info whatsoever on either of the Keling drives. A quick call to keling was uneventful, as the seller couldn't tell me anything but "Yes, very, very good drive!", but sounded happier that I wound up buying Geckos. Might be worthwhile, but I will spend the money and dodge the risks.
