Query: Not a genuine Dell product, but works ok.

Despite being advertised as "a Genuine Dell PA-10 Family 90W AC Power Adapter", this is not a genuine Dell product. It has the exact same size/shape as the Dell unit, but lacks the Dell logo, and appears slightly lower in quality, with a shorter and cheaper feeling cord.The computer doesn't recognize it as a Dell unit either, and gives a warning (both on boot and in Windows) that it isn't genuine and won't charge the battery, and that the computer will run at a lower speed. Despite this, I found that it does charge the battery and the computer runs at full speed.So this is far from a perfect replacement. However, Dell's own units are of such abysmally low quality (I had 3 fail in the first year of owning my laptop), that this one can hardly be worse.Worth it for the price (much lower than buying from Dell), with the above caveats.
