This was an upgrade from a Dunlop DC-Brick, and it is a huge improvement. The build quality is great, and the leads seem much more durable. I also like the added outlet on the side, even though I haven't used it yet. I can't say I notice much difference in the power conditioning department, but that doesn't mean it's not better. Just not such a big change that it stands out. All in all, very pleased with this product.
