Bosch Icon here too. I have had a set on the wifes Infiniti FX35 for 3 years in tropical Florida and they still work fine. I use them on my 07 Roush Mustang as well. Great blades

Maybe someone is telling you that you need a Flex rotary as well? I have one and never use my PC anymore. The slow speed it runs at lets me get in and around tight areas and still have the power when I want it.
