I honestly have not tried any of their recipes but a good suggestion on using any recipe you find online is to run it through SoapCalc to make sure the measurements are correct. This will also let you see the soap quality numbers to verify this is the type of recipe you want. Is there a particular one you are looking at?
The second part of your question I think you were asking about the quality of their products. I think the quality is great as I have been using them the last two years without an issue.
