I've read the review on this site, but has anyone here used them? I like the fact that they have specific colors...panzer grey, rust, etc...

I just got some. Honestly, I was kind of expecting something like artist oils, which are very, very thick and require turp to liquify. The Wilder oils, on the other hand, are already very fluid, and don't need anything added in order to brush them onto your model. The colors are nice, but perhaps a bit less 'heavy' than other oils, meaning less thorough coverage than other oils, which may be a good thing for you, as long as that's what you are expecting. I also happened to get a red Mig Oilbrusher at the same time, and that oil paint, which is similar to the Wilder in being liquified out of the container, seems to have a far greater density and 'covering power'. I'm not sure I would get more Wilder oils, at this point. Hope this helps.

I used one of his browns to make a wash and was disappointed. As noted above, very thin. I thought at first that the pigment had settled out from the solvent and I hoped more solid material would emerge. But it didn't. Using Abteilung matt thinner I found that the component pigments settled out, leaving brown liquid and black sludge needing constant agitating.

I've tried a couple of his enamel washes and found them quite densely pigmented compared to MiG or Vallejo, needing more thinning.
