Has any one ever tried teas imported from Oxalis tea in the Czech Republic.

I found a local company that imports tea from this company and offers them at very good prices and I was wondering about whether they were worth trying. I was wondering about the quality of the base tea they use in their blacks and greens and the quality of their flavourings in black, green and rooibos teas. They do have some ratings on this site, but they are mostly numerical and the only tea company that I have found their teas on is Mandragora. Are there teas worth trying?
