Looks excellent Rob, really brings them up. It's great what you can do with a printer and a piece of paper these days, (where was this years ago!?) Gone are the days of tiny paint brushes and magnifying headbands. These sorts of decals were only mainly available with kits or set sized sheets, and most didn't last long before they disintegrated,- being very thin material.
This modern material is way better, and makes it possible to do whatever your printer can print. Makes models much more realistic, and as you said, can add 'bling' to an otherwise plain object. I've found it indispensable for my R/C planes (and boats to a lesser degree).
