Alvin,
Considering the price and the few problems, I recommend it. It covers a lot of ugly real estate in a big hurry and it's easy to work with but it's not going to satisfy the purist looking to do a VCCA restoration. If you want extra sound deadening and insulation I'd suggest using some of that self-adhesive mat that's sold for that purpose. Just put it down first and then use the plastic panel.
As for the fit issues... it's no different from any other aftermarket stuff you buy and maybe better than most.
