I've noticed a lot of the same things you have all pointed out about Uncurly- the website is a little odd and this thread is a little odd- but instead of posting about it here I contacted them directly. It can be scary to order or try products that don't really have any reviews and aren't being sold on a huge website. After I emailed with them a few times I felt more comfortable trying out the product. From what I can tell they are a very small company just starting out- which if you can imagine is very difficult. Even so they got back to me very quickly and were professional with their communication.
I just tried this product out and I'm posting a separate thread for my review since it's a bit long. I'm really happy with my results, so if you're interested in trying Uncurly out you might want to see how it worked out for me.
