text: It's not great but it works. The first half after clicking on doesn't do anything and then it starts going up after that. The lowest setting could stand to be lower but it's low enough for my purpose. The max load I'm using it for is about 0.5 amps and it seems to handle that amount of power just fine. The connector it comes with was defective, positive and negative were shorted together. I just threw it out because I didn't need it, but I was using it for some testing initially and it took me a bit to figure out the reason stuff wasn't working was because of the connector being defective.
