Nope, I've not purchased them ... but having just installed the OEM Mazda versions, I'll comment.
1. The Rokblokz appear to be flat, conventional "flaps" ... not the molded, sculpted, more stylish Mazda versions.
2. They would be more practical than the Mazdas in our "Northern Country."
3. The concave-to-the front Mazdas efficiently catch and hold our winters' snow, ice, and slush ... impractical, but very stylish.
4. Absent numerous trips to Tahoe, practicality may not be your top priority
P.S. Plus, I'll bet the Rokblokz are much easier to install than the Mazdas.
