I actually headed over to their
thread after learning that they were replacing batches. Good customer service at least, even if it doesn't shout quality control. I think this may motivate them to bring that up to speed.
They have some technical talk about reclaiming solvents, and distillation and the impacts of azetrophs (sp?). I would love to read up more on it, but it has been a long time since high school chemistry, and public accounting doesn't leave a ton of extra time to hit the chemistry books again.
I do have to give them credit at least for offering to replace a bottle that I ordered back in November no questions asked.
