Guardog has come out with a challenger to the Rockerz skate guard - the new line of guards is called "Zigzagz."

Cute - lots of colors; you can order each guard a different color; I'm sure someone will market it with the four-color choices that most retailers offer for Rockerz.
Doesn't say that the Zigzagz take into account the type of blade. I know I'm always asked that when I buy new Rockerz.
I have Matrix blades which got badly scratched by Rockerz so I got a pair of Zigzagz at Christmas. Unfortunately I couldn't make them work on my blades, and they kept falling off so I returned them.
I bought them from Amazon, and had to order them individually. I researched a number of sellers and prices appeared to vary widely, but it was actually because some sellers were selling pairs of guards, whilst others were selling them individually.
