Total Misrepresentation. I ordered (what I thought to be) a DELL charger. See this site: http://www.prontocharger.com/dell-studio-xps-16-laptop-power-ac-adapter-charger/
The site states that it is a DELL charger. Not that it would work on a Dell laptop. It also states that it is originally $62.95 (the DELL website has it for $69.70 so I thought since the original price was that high, it would be genuine Dell)! It was important for us that we ordered a genuine DELL product. When it arrived I realized it is just a very cheap charger! NOT a DELL product. I ended up just purchasing from Dell directly. Prontocharger is a scam. It is false advertising and a misrepresentation of the product. The quality of the poduct, which arrived is very cheap and I would not trust to use it on my expensive laptop.
