I think that there is some simple grammer issues that lend to the confusion.
Inside the
eBay ad, the product is clearly named eDead 45.
The title of the ad says
25^ft eDead Xtreme Car Sound Deadener + Dynamat Roller
That does not mean that the product is called edeade xtreme, but rather it is eDead, which is an extreme sound deadener.
The free Dynamat roller, and the word xtreme will lead to more hit when people search for Dynamat xtreme.
Just some clever wording for advertising purposes, but it does not look like they are calling the product eDead Extreme.
Reminds me of people asking about farad capacitors...
To answer the OP, eDead had some issues inthe past, but I think that eD has done a good job of correcting them. Their customer service seems to be top notch and they have a lot of happy customers.
The eDead 45 is a very thin and light product so you can expect thin and light results, but they do selll an 80 mil matierila that will perform better. Costs more money though.
Remember, you buy cheap, you get cheap. Spend the money on their 80 mils stuff and you will be much happier!
