I used to swear by BOSCH and used them on every vehicle for years, including our CX5...
However, the last few sets I had purchased for our vehicles, the BOSCH did not last at all... then there was the constant streaking, even after trying to salvage the blades by proper cleaning of the rubber blade.
I got tired of throwing money away on the BOSCH. So while out and about one day, I purchased the RainX brand just to try them out. I kid you not and no BS, the RainX wipers from WalMart work perfectly AND theres no streaking at all. The blades have been installed on both of our vehicles for nearly 1 year now... yes, I know, Walmart and RainX, I can hear the jeers already...
But Im telling you all, they work and have not turned to s*** like the BOSCH, plus theyre far less costly too.
For the rear wiper blade on the CX5, I order the replacements from Advance Auto online:
TRICO
Exact Fit Standard Integral Rear Wiper Blade, 14 Inch
Part # 14-A
Price: $12.99
If you use the Advance Auto 20% or even sometimes the 25% off online code, you can surely reduce the cost of $12.99... LOL
