I received the second set of 4 samples I requested. I highly recommend getting the samples before choosing a wood as they vary greatly from the on line photos and even their brochure - not to mention it is the only way to compare them in natural light inside your vehicle. The real woods look better in general in my opinion.
Weight addition? Maybe a few ounces - less than a tall coffee for sure.
I wonder if I loose an echo tree if I use the real wood dash kit!
