Yes I have in fact tried a Krome. I got one from mid tenn hobbies and tried it at home with several paints, thinner ratios, pressures and the like. For a Badger product it is nice, but compared to an Iwata HP-CS or Harder and Steenbeck or Grex, it is sub standard. I would put it in league wirh a Paasche Talon and that is not a good thing for a flagship airbrush!
After test driving it I found the movement was a more than a little rough, still more overspray than with the above mentioned brands, flimsy needle (should have been hardend like an Iwata for that money), far too sensitive with thinning ratios and pressure to be an effective modeling airbrush. Just too finicky. I contacted Badger, trying to get a response from Ken in fact, and was left in the cold for answers and support.
Based on all those factors I decided that there are better airbrushes than a Krome in design, manufacture, ease of use, cleaning and performance. Sorry to pop anyones bubble but you asked for a reply. I think any Iwata Eclipse or higher range, H&S Evolution and over and most better Grex Will be a better airbrush in build, versitility and performance without question. Don't buy hype, buy quality.
Putting as sensitive an airbush as the Krome on your workbech will dissapoint over time. It's not bad, It's just not that good either.
