Bought this because of the price point being 1/2 of a comparable MSD with REV Limiter and 2 Step control. Of course it just ended up costing me more money as I had to buy a name brand ignition box to replace this one after it failed in less than 500 miles.
At first just randomly cut out for a second every now and then and eventually shorted out completely. If you're reading this as part of research prior to purchasing.... DO NOT BUY.
If you've already made the purchase - I hope you have better luck than I did! From looking at reviews on Speedway's & Speedmasters own sites that this box has around 30 to 50% failure rate.
