I bought a pair of these in black. I followed the advice of another reviewer and went a size smaller than I usually go with and they fit perfectly.

This is a horrible product! Sony mistakes in this book. I kept wondering why my answer seemed right but the book had something else and I knew I could add and multiply. Turns out the book was wrong! I will be returning this.

These guys sent me the wrong unit and it took almost 4weeks to get to me . Customer service sucked bad enough that I just cut it and made it fit.

I was worried about this with thick thick hair. I went ahead and bought it to try and had high hopes after reading some reviews. I do not suggest this for thick hair. After spending 20 minutes using it, it helped some, but my hair was still curly and not straight. I'll stick to my babyliss straightener.

I was advised by my motorcycling friends that sea foam is the way to go with engine treatments. They also advised using it prior to storing a motorcycle for anything length of time. Since I live in Florida I don't do much in the way of storing. But this product seemed to live up to its reputation. I even use it in the lawn tractor (which only gets started once every few weeks).
