Let me shed some light on [my] reason of putting "Not Tested in Daz" on my products, which I'm changing, and I will iterate after my explanation.

All my products (aside from dynamic clothing) will load in Daz, but, I use Poser metal shaders a lot of times, and don't use Daz enough to know how to translate them over.

So, I am now changing the "Not Tested in Daz" to "Loads in Daz, but Poser metal shaders are used on (such-n-such) parts," which will let people know that it will load for them, if they have their own metal shaders to use in place of the Poser ones.

I'm not sure of others' reasons, but this is mine, and it shows that just because a product says "not tested in DS", doesn't mean we're too lazy to test it in a free program or whatever, it could just mean that one or more parts/materials don't play nicely in daz, and vendors just put that as a standard disclaimer.
